Hi everyone,
My company is changing VoIP providers. Our current providers system uses the SCCP Skinny protocol for their service so our Cisco IP phones are configured with the skinny firmware. Our new provider uses SIP protocol and we would like to continue to use our same Cisco phones as we love them and do not want to pay for new phones. However, in order to use SIP on the Cisco phones, the firmware has to be migrated from skinny to SIP. Is there a way to do this without cisco files or anything like that? We don't have any of those types of subscriptions...

Any help would be appreciated.

You will need to files from Cisco. Communicate with your new VOIP provider and see if they are happy to download the files for you. From there follow this process:

They say they cannot do that for me. I have gone all over the place but can't because I have no service agreement.

You didn't hear it from me but you can probably find the files on the internet. It might not be the newest version but you can find it

The only files I have found are not complete... They are missing parts here and parts there. Any clues?

I have all three of those files, but when I try to install the EXE it wants a username and password for SQL server... I do not use an SQL server.

Sorry mfranzel, that's the SCCP version of the software, the sip version is "P0S3-07-5-00.zip"

it contains the files listed on the link posted by the first expert. these files will allow you to perform the process in the website.
