Hi guys,

I've set up Gamms SIP trunks using networking mode on an SV8100.
When I try and dial out on them I get an error tone when selecting the trunk, when I dial in i get a busy tone.

I've set up the SV8100 according to the compatablilty report.
on the router (draytek 2820) i've switch off the SIP ALG and have ports 5060 UDP and 6000 - 40000 UDP forwarded to the IPLB.

When running a wireshark trace calling in i get "486 - Busy Here"

Has anyone got any ideas as to whats happening?

Thanks

Stu
