I have got Cisco 7940G IP Phones with the following firmware version.
App Load ID
Boot Load ID
I want to use them with Asterisk 1.6. What do i need to do? Do i need to change the SCCP software to SIP for use with asterisk? if so, then is it possible to upgrade from this version directly to SIP Ver 7.5 firmware (P0S3-07-5-00, i got this firmware).
What is skinny file meant for in asterisk? can the cisco ip phones be used the way Nortel are used through unistim.conf?
What is chan_sccp? is that a solution to my problem?
