Why are Follow-Me calls not signaled?
Question:
Why are follow-me calls not signaled?
Problem:
An XPhone user activates Follow-Me and receives the call on his AnyDevice, but the call is not signaled in the Connect Client and is not journaled at the end of the call.
Possible solutions:
1. The "XccDiversionPattern" must be adjusted, see: https://www.c4b.com/en/knowledgebase/xcc/analyze-xcc-follow-me-problems.php
Explanation: If the Diversion header (see Wireshark Trace) is signaled with prefix or in an unsupported format, this can be corrected with a PhoneToDisplay dialing rule, but this "only" makes the AnyDevice calls themselves work again.
Since the signaling works on a different level, the adjustment of the XccDiversionPattern is required.
2. If the parameter "XccGatewayInPrefix" is used, see: https://www.c4b.com/en/knowledgebase/any-device/forward-on-follow-me-participant-call-is-rejected.php and the E.164 number is signaled with the prefix (+49...99123) in the To header (in the Wireshark trace), the parameter "XccToHeaderFormat" must be set with the value 1 in the Advanced settings of the SIP gateway.
