I have been trying to connect some avaya phones to a cloud PBX we have setup. Avaya is using the protocol h323 instead of SIP, so the usual tricks don't work.
I'm replying myself with the fix for my case in case anyone is interested. Basically you have to remove both the ras and the h323 helpers
This showed me the pointer:
id=20085 trace_id=1730 func=__ip_session_run_tuple line=3241 msg="run helper-ras(dir=original)"
config system session-helper
delete 2 #h323delete 3 #ras
After deleting those helpers, the phone could register without more issues
Thank you aseques!!
Hi, You must remove SIP , H323 , RAS protocols on session helper.
