We have customers using a sipX internal PBX and a Freeswitch device as a softswitch to route calls to our upstream provider, PaeTec. However, the provider doesn’t support the P-Asserted Identity for external call forwarding. PaeTec wants to see a SIP Diversion header instead.

How can we add this header in the Freeswitch device?

 

Thanks,
