external transfer on SIP trunk no audio

[Joe King]

Hi
I have a release 7 MiVB with Gamma SIP trunks. Incoming and outgoing are fine but when a call is transferred or a DDI call forward always to a mobile the call answer bu there is no audio. Wireshark trace does't show errors. The SIP trunks are connected to a MBG in server/gateway so there is no third party firewall.
Played around with SIP peer settings but still no joy.

Any help much appreciated.

make sure local streaming is off on the MBG

If I never did anything I'd never done before , I'd never do anything.....
