Reflashing Cisco IP Phone 7960 from SCCP (skinny) to SIP
Posted on 2011-02-24
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.
