I purcheased this phone off some guy on trademe who was claiming it was 2 talk compatible, on recieving the phone some time ago I found it had the wrong firmware (so it actually wasn't compatible unless you used a cisco IP Pbx) so I got grumpy and tried to get the firmware off cisco, long story short they weren't any help,

Does anyone have access to the SIP firmware for this model of phone that could help me out as I want to have a test with cisco on my system but don't want to buy new as there are other brands that are as good and heaps better value for money, but figured I need to test everything,

If anyone can help it would be hugely appreciated

It doesn't take long with Google to find the SIP firmware for all the 79XX phones.

Having that that I'll be completely honest with you and say that if you're unable to locate this your chances of actually getting the phone going using SIP are pretty close to non existant. Once you have the firmware you'll need to configure a TFTP server, manually create all your config files by hand with the correct names and then configure the phone to download these using DHCP option 66.

Once you then have the phone configured you'll probably then have to deal with some fairly common NAT issues and then decide these phones are horrible buggy devices on non Cisco SIP hardware and were really only designed for a Cisco CM environment.

There are plenty of issues that make these phones less than ideal in any other environment and you're far better off opting for SPA5XX phones for SIP.

I had pretty much figured that would be the case, sadly not even the magic google could help with firmware but thought I'd give it one last go, I got some IP phones from China for about less than the cost of an interisland courier and they have been mint so might just stick with those, Oh well might put an axe through it and sell the power supply as the phone itself is useless,

Cheers

If you're using them in an Asterisk environment they're OK phones as you can use auto provisioning to configure everything.
