Why are follow-me calls not signaled?
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.
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.
