Hi All
I am configuring the Remote worker scenario on a FreePBX system. I followed the scenario but can not get it to work. Usually I will get either a 404 contact no found or a 405 method not allowed. Removing the FreeSBC from the flow allows the remote phone(s) to register successfully.
Below is a small tcpdump of a registration attempt which failed. I took it from the outside view and one from the pbx server itself.
Can any one help?
