Bitrix24 Call Tracking allows using SIP PBX numbers (SIP connector required).
Click Telephony > Configure numbers > select SIP connection > SIP PBX numbers.
Enable the Get destination number from SIP headers option to automatically detect your SIP PBX numbers and use them in Call Tracking.
How it works
SIP uses special headers containing the information about the destination number.
These headers are saved to the log file. You can view call logs in the Call details section.
Information about the destination number is stored in diversion and to headers.
Information in these headers may vary depending on SIP PBX settings, so you can specify the order in which Bitrix24 will check headers (Header priority).
What happens after the number has been detected
Bitrix24 automatically adds the detected number to the Sales Intelligence > Call tracking section.
This number can be assigned to any traffic source.
