I am having issues with a sip trunk I have setup, when you receive or make a call you get 20 seconds working ok then 10 seconds one way speech (inbound speech not working)then 20 seconds ok and the pattern continues, all the usual ports are open/forward and sip alg is off on the Draytek router????

Wireshark it, if you can play back the call with full audio it's the system, if not it's the router/provider. We have many Hipcom SIPs through Drayteks but have never seen this issue though. Occcassional (2/3 times a month sometimes) total trunk loss as the Draytek NAT table fills up/corrupts.....but not this
