I seem to have an issue with the system when I try and register more than two trunks. I have six trunks I had registered OK with my previous setup on PBXIAF however there seems to be and issue now. I have two trunks from a UK provider #1, a single trunk from UK provider #2 and three trunks from a Canadian provider. Currently the first two UK providers trunks are OK, registered and call in and out, however whenever I try and add any of the others the system drops all registered trunks and extensions, nothing will connect. The reports keep showing failed registration and the Asterisk Info shows the trunks as UNKNOWN or UNREACHABLE. I think it is something daft. Any ideas out there.
