Remote Workers - No Registration Empty Remote Workers - No Registration

Post by juanh on Sat Jan 05, 2019 1:57 pm

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?

Thanks for the reply, but they didn't help.  

This may add more light to this.  I am adding a few more tcpdumps to see if it helps:
