Hello,

I have a setup where Freeswitch is a transit PBX between the public world and two internal PBXes - one is another Freeswitch and one is Cisco CUCM. All connections are SIP trunks.

The issue is that the external world SIP trunk sends the real called party name in the "200 OK" in the P-Asserted-Identity field. At this stage, the "transit FS" sends also OK without the received called party name, and then the behavior of the two internal PBXes is different:

When the internal PBX is FS, the transit FS generates INFO message and places the updated called name in X-FS-Display-Name field.
When the internal PBX is Cisco, nothing is sent, thus the true called name is not displayed.

Any idea how to force the transit FS to send it to Cisco as well?

Thanks, __yehavi:
