I am attempting to setup some Nortel 1140e unistim phones. I have located the Unistim.conf file in Asterisk 1.6 When I start up the phone it can recognize the server but I receive the following message: Sorry this phone is not registered in Unistim.cfg and gives me the MAC address. I have place the MAC address in the config file and set up an extension for it and get the same result. Has anyone been successful at using unistim in Asterisk 1.6?
