Dear fellow list readers
This is the situation:
ISDN Devices => Patton ISDN to SIP GW => Asterisk PJSIP

The ISDN Devices behind the patton have different MSN and should be able to send them in the From: Header, so the default endpoint identification mechanism which matches the From username with the endplaint fails.
So what are the options to solve that issue?
I see the asterisk sending out a challenge and getting a proper reply from the patton, but then stills complains about the endpoint not matching.
According to the manual there is no
