An update:
The problem is in asterisk 1.6 but also in my router. In the former, it is the variable, type and insecure. But also note that router issue is important. Because of using more than one IP, when the outgoing connection is made, different IPs may be associated. In return at the authenization phase, IPs mismatched. Now I fix this by looking at my outgoing firewall rules, and bound to a fixed wan IP . No problem so far.
The usual internal extension under one asterisk server works with the present auto-attendant script. When try to press extension of other asterisks or try other dialplan, it generates invalid extension. |
