7960 phone on pure SIP platform?

[RLSbutton]

I have acquired a Cisco 7960 phone that I would like to run at home on a SIP standalone platform with a SIP carrier. Can anyone help or tell me if this is even possible?

Who do I have to contact at Cisco in order to get a license to make this work?

I can't just call Cisco and buy the license as they say I have to be a preferred partner. I've called local Cisco vendors and they say I need to be a business in order to run a Cisco phone at home.

One vendor even told me to go out and buy an analog phone and use an ATA adapter for my SIP service, because I really don't need a complex Cisco phone at home. That is besides the point, I currently have Nortel BCM at home and everyone at Nortel/Avaya has been very helpful and they understand that experimenting with SIP is a hobby for me, I don't understand why Cisco isn't? Plus I have the phone and power brick and now it's just dead weight. Can anyone help?

I think I'll just sell the phone on ebay!

Are you a cco registered user? If so you can download the sip software from there. The procedure is well documented on how to oonvert from sscp to sip.
From what you are saying you are not a registered user otherwise it would not be an issue for you.
The reason a cisco var does not want to sell you the software besides that you are not a business is that they do not want the headache for a couple hundred bucks.
You are already complaining that you have a dead weight on your desk. Imagine when you buy software on top of that and you are unable to get it to work.
You'll be asking either for the money back or for the vendor to support you for free since they sold you the software.
I understand that you are trying to learn and appreciate that. I think you best bet is to keep calling cisco resellers until you find someone willing to sell you that or find someone on ebay to purchase illegally.

Thank you Whykap,

I forgot that one of my counterparts from college is a registered cco user and contacted him. He is actually been looking for a way to test SIP and he is glad I called him and we are attempting to install the sip firmware 8.4 on the phone. The problem is that when the phone reaches the second TFTP download, an "undefinable error" occurs and the phone restarts. We are thinking that since the phone is a later model from sometime around 2004, that the newer firmware is not agreeing with this phone. We are going to keep trying.

[whykap]

the release notes for the firmware should tell you what devices it supports. You are on the right track however

Thank you again Whykap.

I also noticed that the phone already has SIP configuration downloaded as one of the setting options under Settings. This makes me assume it has already been converted from SCCP to SIP. Can you have SIP configuration under the SCCP protocol or does this more than likely mean that the phone is SIP compatible? I am going to go ahead and point the phone back to the original inactive TFTP server (so it doesn't keep resetting) and bring in a cfn. file and try to register with my sip provider on the old firmware.

If you have SIP settings then it has SIP firmware already. Give it a shot as is.

I am close, I keep getting a message saying "That number has not been assigned yet." I've entered the voip.ms authentication and password, but calls still are not completing....but I have made some progress.

Whykap,

After I sent you the message last night, I was able to place calls to other DID numbers I have on the voip.ms site, but incoming calls are giving me "an all circuits are busy" message. I also cannot dial anywhere other than voip.ms account, my SIP carrier. They say they phone has not registered with them yet. How can I register the Cisco phone?

Thank you.

If you are making calls then it must be registered somewhere. Every service provider works their SIP in a unique way so the best thing to do is work with them and see why you can only call within their network.

Hi Whykap, I was able to register with my SIP provider and now make calls. Interesting enough though, the DID works for the first 3-5 minutes the phone is reset and restarted, but the DID's stop working and I can no longer call into the phone. Is there a way to set a "keep alive"?

[whykap]

Can you make outbound calls when inbound doesnt work ?
if you reset the phone does it work?
Is there a firewall in the picture?

 

[RLSbutton]

I called the SIP carrier and it was a problem on their end. They set the Keep Alive on their Call Server and problem is now solved!

One Tip that I have had with Cisco sip phones,
If they are behind a Cisco router with CBAC enabled you need to do the below commands on the router to get them working:

no ip nat service sip tcp port 5060
no ip nat service sip udp port 5060


Firmwares are also important
