Hello,
I have one audio issue with our SIP trunk through the CUBE. The problem is that we have two interface in our CUBE one for signaling and one for RTP, and during the call setup our CUBE is sending the signaling interface IP address as media address where SP should send us the RTP, and this both signaling and RTP interface they are not routed from SP. How can I let the cube to send the IP address of the RTP interface so that the SP can send their RTP truffic to that interface.
The configuration is as following:
voice service voip
no ip address trusted authenticate
address-hiding
mode border-element
allow-connections h323 to h323
allow-connections h323 to sip

I have tried to bind the media source-interface with G0/1.2 but this didn't help, also from the debug ccsip media we can see the CUBE is sending the signaling IP address as source of RTP packets:

Many thanks,
Nizar
