[Freeswitch-users] Need help cc Gateway (SIP trunk) setup for provider using Auth ID

[Alexander Harm]

My SIP provider uses
- User ID (same as Caller ID Number)
- Password
- Auth ID (different from User ID)
for registration. I have to admit that I'm completely at loss on how to configure freeSWITCH using Auth ID. I tried all combinations I could think off but I just keep getting 403 error messages.
Help is very much appreciated.
