IAX2 firmware for Cisco 79xx IP phones - Does it exist?


Would like to move our Cisco phones from SIP to IAX2. Wondering if there is any IAX2 firmware for Cisco that I can download?

Thank you in advance for your help.


I am highly in doubt of such. I can almost bet there is none. Jusy don’t count on it.

No, there are no IAX-firmwares for Cisco 79xx phones. Only SIP or SCCP from Cisco.
