Release Notes
v5.1.6.0 | 21.02.2025
Improvements to the Delta Tel:
Fixed Delta Tel bugs:
- Delta Tel has added the ability to create scenarios (templates) for communicating with customers in chats to standardize and improve the quality of interaction with the help of pre-prepared answers to common questions. The system will search and offer options for answering customer questions based on keywords in the message text.
- We divided the implementation of the third step of the migrator into three stages: DialFlow > CallFinishResults > DialStages. When launching the third step, the settings provided an opportunity to choose the execution of the entire process or step-by-step execution.
- In Delta Tel, the “User name” column on the “Management > Chat history” tab was removed, as the column was a rudiment and was not used in the system logic.
- In Delta Tel, the “Automatic greeting” functionality on the “Queues > Incoming queue > Conversation block” tab was removed, as the functionality was a rudiment and was not used in the system logic.
- In Delta Tel, two new columns “Queue Id” and “Queue Name” were added to the “Control > Call Records” tab for convenient filtering of the found records.
- In Delta Tel, two new search variables “Queue Id” and “Queue Name” were added to the Control > Call Records > Call Records Search Window tab.
- In Delta Tel, the time of the minimum step of the dial and channel cleaning worker on the Debug tab was changed.
- In Delta Tel, the logic of transferring related items to Freeze during ApiClick2Call calls was improved. When making calls via ApiClick2Call, all related items with the number we are calling will be set to Freeze status regardless of the queues they were in.
- Delta Tel added the ability to add an avatar in the user settings for further display in the system.
- In Delta Tel, a new search has been added to the window for distributing trunk settings, which makes it possible to search both by trunk name and by its ID.
- In Delta Tel, the display of the “Queue greeting” settings parameter for the “Call/Call” blocks has been added.
- Delta Tel has changed the logic of item processing in APIClick2Call calls. If the item was archived or had the status “Processed” or “Canceled” before the call started, after the call ended, regardless of the success of the dialing or receiving the result, the item will return to the inactive status it was in before the call started.
- In Delta Tel, the functionality “Store temporary AMD recording files” on the “Settings > Server Settings > General” tab was removed.
- In Delta Tel, the restart worker was removed from the server.
- In Delta Tel, the application's RAM usage was optimized.
Fixed Delta Tel bugs:
- Fixed a bug that prevented the report “Operator statistics” from loading on the “Statistics > Operators > Excel reports” tab.
- A bug has been fixed in which when connecting a subscriber to an operator, the call time was logged to the Connecting stage of the DialStages table.
- A bug has been fixed in which Delta Tel did not clear project fields during the general recalculation.
- A bug has been fixed in which the slider on the Online > Calls tab could be moved from the visible part of the screen.
- Fixed a bug where the “Dal.SaveWithInt32IdentityAsync” error occurred when opening the “Management > IVM Configuration > IVM clips” tab and adding an audio recording.
- Fixed a bug where the general recalculation led to the accumulation of fields in the application memory when the dailer was active.
- Fixed the “NullReferenceException” error that occurred when clearing the image in the chatbot directory and opening the chat history in the “Management > Chat History” tab.
v5.1.5.2 | 26.01.2025
Improvements to the Delta Tel:
Fixed Delta Tel bugs:
- In Delta Tel Client, the ability to view attached photos in chat history both in the dashboard on the “Online” tab and in the “Administration” section of the Chat History.
- In Delta Tel Client, the size of images of attached photos in the chat history has been increased when hovering over the cursor.
- In Delta Tel Client, an option was added to configure the distribution of calls to operators after marking the results in the CRM, if the call has already been completed. Thus, after the call is completed and the result is marked, the application distributes a new call to the operator, ignoring the time of filling out the customer card.
Fixed Delta Tel bugs:
- The script that caused an error if you add the “variable from database” function block to the IVR strategy has been fixed.
v5.1.5.0 | 27.12.2024
Improvements to the Delta Tel:
Fixed Delta Tel bugs:
- In Delta Tel Client, the ability to restrict changes to PjPhone settings/configuration by setting a password in the “Server Settings > Communication” tab was added.
- The logic of the migrator when updating Obsolete tables has been changed, which will allow updating tables in batches, one by one.
- Delta Tel added error handling when sending empty files via chat.
- Delta Tel has added the functionality of sending requests to open a customer card in CRM when an operator receives a chat.
- The ability to view image attachments in the chat history in Delta Tel Client has been added.
Fixed Delta Tel bugs:
- Fixed a bug when the migrator did not create the FilterIdListTableType table type.
- Fixed a bug when the operator's status “Break” was not taken into account in the statistics on the “Statistics > Operator Statistics” tab.
- Fixed a bug where the field name was not changed when adding a field to the project and trying to change the name on the “Settings > Fields” tab.
- An error was fixed when an incoming queue could be added to the list of queues of the “Sending call result” functionality without the “Incoming” queue type activated on the “Settings > Server settings > Communication” tab.
v5.1.4.0 | 18.11.2024
Improvements to the Delta Tel:
Fixed Delta Tel bugs:
- Delta Tel has added the ability to initiate writing data from the application memory to the database when the Delta Tel server is closed or restarted. Since a large part of the data is stored in the application memory and is written via bulk at a certain time interval, an emergency restart or shutdown of the application could lead to the loss of this data.
Fixed Delta Tel bugs:
- Fixed a bug where the “Number of lines” on the “Info” tab was equal to 0 if the “Predictive” mode was set and the “Number of lines” parameter was set to more than zero.
- Fixed a bug that prevented the statistics of calls by queues from being loaded on the “Statistics > General statistics” tab.
- Fixed a bug that caused the AMD service to generate an exception message when recognizing answering machines.
- Fixed a bug where MSI Delta Tel Client did not build when selecting the project “DeltaM.DeltaTel.ClientSetup”.
- Fixed a bug where after restarting the server, the list of selected queues for sending the call result to the selected API point was cleared on the “Settings > Server settings > Communication > Send call result” tab.
- Optimization of CPU threads usage was made to allocate more resources to the dailies.
- An error was fixed when two operators received the status “Filling the card” when transferring a call between operators on the “Online > Auto-call” tab.

- The migrator has adapted new scripts for database versions below 2012
- The CFR_DialFlowID.sql script was added to the migrator
- Delta Tel has changed the format of newline feeds for Unix systems when creating a trunk pinning file for manual calls on the Asterisk server.
- In Delta Tel, spu_rep_ReportOperators for SQL server was added. The unification with the use of the function in the sql server has had a positive impact on the speed of script execution.
- The use of built-in fonts for generating system reports was unified in Delta Tel.
- In Delta Tel, it was added the implementation of saving data to the DialFlow table not through BulkCopy but through Insert/Replace to prevent data loss that could occur due to duplicate dialogs in the handler.
- A new block of the “API request” strategy was added to Delta Tel to be able to pass variables to external API points to launch trigger chains in external services for sending SMS messages, e-mail, etc.
Fixed Delta Tel bugs:
- Fixed a bug when telephony strategy blocks were stacked on top of each other after updating.
- A bug was fixed when it was not possible to minimize a group of queues in the filter when grouping was activated on the “Queues” tab.
- A bug was fixed when the Delta Tel server did not work if the directory was missing or the path to the ssh/sftp file was incorrect.
- Fixed a bug when the queue mode was changed to “IvmAlgorithm” when adding users from this queue to the user group.

- An issue was fixed when there were cases of hung calls on the Online and Debug tabs.
- Fixed a bug when the operator status was displayed as “In conversation” on the “Online” tab in Delta Tel Client while there was no conversation in Pjphone.
- Fixed a bug where new users were not saved after adding them to Delta Tel Client on the “Settings > Users > Add” tab.
- Fixed a bug where the RetryCount change for calls in the DialFlow table was incorrectly recorded in the database.
- Fixed a bug where the “Duration” field of the call duration value in the “CallFinishResults” table was NULL when initiating APIClickToCall calls.
- A grammatical error was fixed when logging the “ManualCallHangupHandler” in the Delta Tel server.
- A bug was fixed when Sip and operator name did not change after transferring a call between operators on the “Online > Calls” tab.
v5.1.2.0 | 30.09.2024
Improvements to the Delta Tel:
- In Delta Tel, the statistics worker was optimized to reduce the load on the system by reducing the number of database queries.
- In Delta Tel, the ability to select queues from which the system will send data on completed calls via API has been added to the Settings > Server Settings > Communication tab.
- In Delta Tel, the ability to display a trunk or a group of trunks that have been assigned to users to make manual calls via the Click to Call API has been added to the Settings > Users tab.
- In Delta Tel, the ability to configure trunks or their groups at the user role level or at the user level, which will be used during manual calls using the Click To Call API, has been added.
- The logic of the application server startup was changed in Delta Tel. In the absence of a license key, the Delta Tel server should still start.
- In the Delta Tel migrator, the index was removed from the obsolete.DialFlow and obsolete.DialStages tables to prevent an error that can significantly delay the speed of updating sites
- Delta Tel has added the ability to configure the transmission of the WorkItems.KeyID variable on a call, for further transmission of this variable to Asterisk. When the functionality is enabled in the Action: Originate in the variable field, the system passes the KeyID variable from the WorkItems database table.
- Delta Tel has added the ability to restrict the transmission of statuses to PjPhone when it accesses the hub. To prohibit the status transmission, you need to activate the “Do not transmit status to PjPhone” checkbox on the “Settings > Operator statuses > Status settings” tab.
- Delta Tel has added an API point that initiates a schedule and queue status check and returns the check result in response to a request.
Fixed Delta Tel bugs:
- Fixed a bug where the “Debug” tab did not open when right-clicking on the client version and restarting the Delta Tell service.
- Fixed a bug where the settings of two autodialer modes were mixed, which led to the stopping of automatic calls in the queue.
- Fixed a bug when the Exel report “Operator Statistics” on the “Statistics - Operators” tab was loaded empty.
- Fixed a bug where the application tried to save a duplicate of the call completion result when it was received.
- Fixed a bug in which the IsNotVisibleStatus column in the UserStatus table was not created after performing a migration to postgres db.

v4.1.1.0 | 20.08.2024
Improvements to the Delta Tel:
- An alternative script for SQL server below 2017 was created in the migrator Migration_UpdateProceduresAndFunctions.sql
- In the Delta Tel database, obsolete Dialflow, CallFinishResults and DialStage were updated using packages to reduce memory usage.
- The existing SQL functions were updated in Delta Tel to optimize resource utilization and improve statistics loading.
- In Delta Tel, the ability to transfer the necessary operators to the “Offline” status via the Delta Tel Client interface in the “Online > User statuses” tab was added.
- Delta Tel added the ability to automatically fill in the product version in the configuration file when building application files. Thus, only the current version of the client and softphone can connect to the current version of the server.
- Delta Tel added an option to send a request to open a customer card when transferring a call to another operator.
- Delta Tel has optimized the uploading of call records on the Control > Call Records tab, which significantly speeds up their uploading in the interface.
- Asterisk version checking has been added to Delta Tel when the application server starts. When you try to start the application server, Delta Tel makes a request to Asterisk to get its version. If the version received from the PBX and the version specified in the application configuration file do not match, the Delta Tel server will not start. In this case, an error of Asterisk version mismatch will be recorded in the log file.
- In Delta Tel, the API point api/v1/Import/ProcessPhoneNumberResult has been extended. An additional parameter “UserdID” (CRM ID of the user who added the action to the card) was added.
- In Delta Tel, the logic of recording the Trunkid field when an incoming call is received has been changed. From now on, the IncomeCall event of the “trunkName” field will be compared with the existing trunks in the “Trunks” table of the “Name” field.
Fixed Delta Tel bugs:
- Fixed a bug where call data was not written to the DialFlow table due to duplicate GUIDs, and additionally generated error spam.
- Fixed a bug where CallFinishResult duplication occurred when using the InternalCollectionClearing worker handler.
- Fixed a bug in which the CallFinishResult value was not written to the database when the operator transferred the call and added the result to the card on the CRM side.
- Fixed a bug where the CallFinishResult value was not written to the database when sending the CRM result without “DropCrmResult” during the call.
- Fixed a bug where the system could generate a non-original GUID for recording call data.
- Fixed a bug where the “Comparison” block had no values when the “CallFinishResult > FinishReason” value was set in the “Condition” block on the “Queues > Strategy” tab.
- Fixed a bug where the name “Active user in the queue” was cut off if you set the localization to ru and open Delta Tel Client in low resolution on the “Queues > Information” tab.
- A bug was fixed when internal calls between third-party PBXs hung on the “Online > Dialing” tab.
- The bug that caused a decrease in call intensity was fixed.
- Fixed a bug where dialing from the queue for missed calls was not performed because some elements of this queue did not have a ProjectEntityId created on the incoming line.
- Fixed spelling errors in the IVM settings when setting lang “UA” on the “Queues > Strategy > IVM Unit” tab.
- Fixed a bug when the call hung with “dial.WorkQueueId = null/workItem = null” and followed the “GotoIvmErr” logic.
- Fixed a bug where the user did not return to “WaitParking” after becoming reachable and being in the “LeaveParking” status.
- Fixed a bug where the number of items was not updated when clicking the “Cancel items” button on the “Queues > Select items” tab.
- Fixed a bug where, when the logic for opening a customer card after redirection was disabled, two records per call were added to the CallFinishResult table in the database.
- An error was fixed when the list of domain groups was not loaded into Active Directory if the “Suffixing” functionality was disabled on the “Settings > Roles” tab.
v4.1.0.1 | 11.07.2024
Improvements to the Delta Tel:
- A new index IX_CallFinishResults_DialId for the CallFinishResults table was added to the Delta Tel migrator.
- In Delta Tel, the logic of creating calls was optimized, which led to a change in the data type of the DialFlowId identifier in the database. From now on, the DialFlowId identifier is generated in the application memory when a call is initiated in the form of a GUID and is written to the database along with the call data after the call is completed.
- Delta Tel has optimized the sending and calculation of statistics on the Online > Auto-dial tab. At startup, the server downloads aggregated call statistics for the current day and groups them by queues. Then the server aggregates this data in memory and displays statistics according to the calculations. The same is implemented for operator statistics in Pjphone.
- In Delta Tel, the display of the total number of items for a given filtering field has been added to the "Queues > Item selection" tab.
- In Delta Tel, the ability to record the date of adding trunk numbers in the template on the PBX after they are saved on the "Management > Provider numbers" tab has been added, which allows filtering, comparison conditions and selection by the specified dates.
- Delta Tel has added a checkbox for the "Predictive" mode to check the assigned operator, which makes it possible to distribute the call to the operator assigned to the agreement in the first place if there is an available operator assigned to the agreement.
- In Delta Tel Client, the "Created date" display for trunks has been added to the "Settings >Trunks" tab (based on the data in the dbo.Trunks.CreatedOn table). The new field allows filtering, comparison conditions and selection by the specified dates.
- Delta Tel has added the ability to prohibit outgoing manual calls (Click to Call API, Click to Call, manual call from PjPhone) when operators are working in automatic statuses (auto pickup, online, incoming call) by activating the "Prohibit manual calls" checkbox on the "Settings > Operator statuses" tab.
- In Delta Tel, the "Recalculate all queues" functionality has been moved from the "Queues > Select items" tab to the "Settings > Server settings > Basic" tab. This functionality can be used accidentally instead of the "Recalculate" button, which causes the update of the status of items in accordance with the database, which is a functionality that should be in the settings.
Fixed Delta Tel bugs:
- A bug was fixed when the remove and drop functionality did not work on the "Online" tab.
- Fixed a bug in which the basic Delta Tel ports were always available in the checker if you write them without "http" and click the "Check" button.
- Fixed the "InvalidOperationException" error that appeared when deleting a trunk from the queue and changing the trunk name on the "Settings > Trunks" tab.
- Fixed the "NullReferenceException" error that was thrown when an item was placed in the "Cancel Items" block on the "Queues > Strategy" tab.
- Fixed a bug where custom fields lost their values when passing through the "Set" block of the strategy during recalculation.
- Fixed a bug where the IVM block settings disappeared when trying to move it lower in priority on the "Queues > Strategy" tab.
