Cisco 7912 using SIP


<p>I just bought a Cisco 7912 phone and it is configured to use CallManager servers.<br />

I would like to use it with my SIP phone line, is there any way to do this?</p>

<p>Thanks in advance,<br />



Re: Cisco 7912 using SIP

The 7912 doesn't support a SIP phone load.


If it's actually registered to CCM or CME, then you can use your SIP trunk directly there.


Otherwise - sorry.  Need a 7940/60/70/41/42/71..etc

Actually there is SIP firmware for the 7912 (latest is 8.0.1), but is not released to the public by Cisco. You will also need the configuration utility to generate a .cfg file from a text file, in order to upgrade.  The configuration utility is also licensed software.

Yep - looks like your right on this.  Didn't check.


But, it is actually available on for download.  If you have the contract rights, you can take a look at this link:


(Not sure if that link will pull up for you, go to voice downloads and do a search for 7912->SIP software).  Thanks Paulo.

Hi, I said "not released to the public" to mean "need a paid support contract to download". Usually people buying or inheriting used cisco products do not have one.

Thanks for the nice rating and good luck!
