I am trying to configure Avaya IP phone 1616 and 1608 models with asterisk server. The phone is able to fetch the configuration files from the server web directory after we set the manual IP configurations on the phone. But after that the display shows as discovering X.X.X.X(Server IP) and not able to register with the SIP extensions.
asterisk version - Asterisk 16.13.0
Can anyone help me to crack this?
Thanks in advance
