Cisco ASA 5505 8.2(3) voip no audio

Hi,

i am struggling to get any audio when ringing from the outside pstn to an internal phone.

we have a pbx service on the outside connecting via sip to an internal gateway. we see the sip trunk is up and we see udp connections built successfully when making a call but there is no audio despite data increasing.

we have the internal network PATted to a single outside interface IP.

i have tried various methods of:

enable/disable sip inspection

enable disable inbound acl permitting all ip traffic from sip provider to outside interface ip of ASA

what is the recommended configuration for such a setup? do we need to enable 1 to 1 nat? should we enable / disable sip inspection?

any advice appreciated!

Mario

further looking in to this i have stripped the config right down.

i now just have a static PAT for udp 5060

and then an inbound acl permitting all udp traffic

inspect sip is disabled

and the sip trunk wont even establish properly now.
