VTC video but no audiocall

I have a Real Presence group 500 connected to a sound station 7000. We got the Videoconderence to work, but i cannot make an audio call. it does not get a dial tone, it just drops the call completely and a messege comes up that reads 


"your call could not be completed as requested because the immediate network cannot be found. contact your network administrator for assistance"- what does that mean?


Am I missing something in the set up? Network team believes their settings are correct, and the Polycom is registered to the CUCM via SIP.
