i was wondering if cisco 7911 phone could work on an Asterisk PBX (SIP mode)??
In Cisco Site the firmware for the 7911 to support SIP is used for upper versions of CCM 5.X, but there is no mention if the firmwares proposed are used to work with Asterisk or other SIP PBXs !!
Plz i need urgent help. Thx alot.
