I try to recive incoming calls from a gateway using FS without external profile....
I would like to use just one profile, and route incoming calls based on DID-s and context,
just like in asterisk...
But FS always logs:

sofia.c:8834 sofia/internal/13245678@1.2.3.4 receiving invite from 1.2.3.4:5060 version: 1.4.14 sofia.c:9001 IP 1.2.3.4 Rejected by acl "domains". Falling back to Digest auth.

sofia_reg.c:2827 Can't find user [2000@192.168.101.44] from 1.2.3.4
You must define a domain called '192.168.101.44' in your directory and add a user with the id="2000" attribute
and you must configure your device to use the proper domain in it's authentication credentials.

I do not need any users at all...

I just need to recive calls from a gateway and route them to specific context/extension in XML dialplan...

How to do thet?
What is the context parameter of the gateway is used for, if not for that purpuse?

Thanks,
John
