In sql.txt, 8400's domain is p3t1.zone1.sip and yet he log's on as 8400(a)zone1.sip Try updating the domain of 8400 in mysql to zone1.sip. Not sure if this will work. But give it a try. Your config file looks ok to me.

I'm new to using this board... Anyways, just wanted to see if anyone has an answer for us, cuz it's really a very simple issue. We think that it's probably something really simple, but we are too near-sighted to see it. :) The problem again is that the softphone cannot login to the SER? You can see that the user 84000 is created in the mysql database (sql.txt.) WE've also turned on all the necessary auth_db lines in the ser.cfg Also attached is the ngrep capture of the register, 404 fail, register w/ digest, and 404 fail again... (notworking.txt). Thanks!
