Hi HB9EUE, 73! This is a pcap file that i got with sngrep, a simple call with two client without voice:

I think the problem is precisely the fact that the two clients do not communicate with each other. If you can confirm this by the pcap file, is there a way to force the clients to transmit and receive the voice throught the SIP server intead of from a direct connection? Thank you in adavance
