question about remote ip phone can't dial out to PSTN

Problem description:

Local Cisco2821 with IOS12.3(14)T and CME,more than 20 local ip phones(Cisco7940) and 3 remote ip phones (Cisco7940,connected through vpn) regiested to this router.

All 7940s can call each other successfully,but only when the 3 remote ip phones dial out to PSTN,"connected" in the caller's phone screen, the called phone(include mobile phone) can receive the call,ringing,pickup the handset,but no voice can be heard.

Remote phone:extension 5297/5298/5299

Local phone:5201/5201/.....

test:

5297 dial 5298 and 5298 dial 5297,it's ok.

5297 dial 5201,it's ok.

5297 dial out to PSTN by dial "9,63912848" or "9,mobile phone number",the called phone ring,pickup,no voice.

Why?

Re: question about remote ip phone can't dial out to PSTN

I think this is due to the phone load. Try using a different IP phone load.
