We register 2 SIP softphones to CME and they work correctly if they call an SCCP phone or are called by an SCCP phone
or if they receive a call from an incoming SIP trunk or if they call with an outgoing SIP trunk
if they call each other no voice is heard.
We see that the RTP packets are sent to CME but CME doesn't forward the packets to the other phone.
The addresses, port numbers and so on are correct, the RTP connections are shown as working BUT the packets
are not forwarded.
Does anyone has a suggestion to try?
Thanks a lot
