Last week I ‘accidentally’ bought a Cisco 7911 phone on Ebay. My bid was low, the device was missing a few bits, but I still thought I wouldn’t get it.
Suffice to say… I’ve just written this piece on how to load the SIP firmware onto a Cisco 7911 phone. The procedures are covered elsewhere, but I thought I could compress it into a format that’s slightly easier to understand. Hope it makes sense. 🙂
Whilst I’m at it, if anyone can email me a working SIP based cnf.xml file, it would be greatly appreciated. Getting the firmware onto the phone is easy… configuring it for Asterisk seems to be a completely different ballgame.
