I purchased a couple of used Cisco 7960 phones online to use with a hosted VOIP provider. However, the VOIP provider is asking me to have the latest firmware installed on the phones. Currently, the phones are loaded with SIP firmware POS3-7-2-00 and the latest is POS3-8-12-00. I tried to go to Cisco for the firmware but I came out of that interaction pretty confused and without a firmware solution. Would it be difficult for me to upgrade the phone myself with very little VOIP experience? I already managed to download the latest firmware from the web. Now I just need to know how to get it into the phone. Any help would be greatly appreciated.
