I am wondering about how to get the SIP firmware for the 7940g/7960g phones. I have been told many things by different people and need some clarification from Cisco directly. I was told first that it could be downloaded from the cisco website but when I tried, I was directed to a page which stated that it requires a service contract. I was also told that it could possibly need a sip license from cisco on top of the service contract.
What I would like to know is if I am using the Cisco 7940g/7960g phones with a third party PBX, can I simply purchase 1 service contract to download the image or do I need to purchase a service contract for each device. Also, how do I track each device if I am in an organization with hundreds of phones?
Any information would be greatly appreciated.
