I have now set symmetric nat internally and externally for ports 5060-5061 5080-5081 and 30000-31000. I still get the same problem of the inbound call failing on pickup.
I have tcp dumped the ITSP registration process and i see the pbx asking for a reply on 5080, but instead i see the ITSP (aql.com) replying on 5060. Is this the ITSPs problem, would a fix be to use another UK based ITSP (any recommendations?)
