Hi List,<br><br>Ive got a bunch of Avaya IP9640 that we want to convert to SIP and then hook up to Asterisk so we can dump this overpriced Avaya system. Ive got ahold of the SIP firmware, but I cannot find anything on how to convert the phone itself to SIP, when I go into setup mode it wants a "command" which im guessing is the program code like the rest of the Avaya systems works. Has anyone been able to convert this to SIP and if so, any suggestions for me?<br>
<br>Any help would be great, Ive Googled and have found a bunch of dead ends.<br><br>Thanks!<br><br>
