Hello,
As background I have two different SIP providers with different phone numbers. I have successfully set up my FreePBX server on AWS with one of my SIP providers, everything works together with all the voice recordings, time conditions, etc.
The problem that I’m having is with the second SIP provider. I am not able to get the correct configuration on the trunk setup for them, and their support is not being helpful. After much trial and error I’ve managed to get a successful “105 registered” status for the trunk, however, I am not able to receive or make calls. Everything goes straight to the SIP provider’s own voicemail.
As a quirk, this SIP provider provides a separate “authentication name” and “username”, the username being 5 numbers and appearing to be more like a kind of extension, and the registration only succeeds with the following registration string:
[authname]:[password]@[host domain]/[username]
This SIP provider also separately provides a 3CX service that allows me to take and receive calls on their web interface. However, I have confirmed that the SIP configuration details that they have provided me successfully works on third party VOIP softphones and deskphones very easily.
I have tried (unsuccessfully) virtually all the combinations that I’ve found online in the outgoing and incoming tabs of the FreePBX SIP Settings, does anyone have a clue on which PEER details and USER details will work? I think I may have to set some wonky settings because of the separate authname and username.
Thank you!
