Long shot: Can anyone here help me with configuring a Cisco 7821 phone so I can connect to a non-Cisco SIP provider? It seems that this is not officially supported but kind of works for some people with the specific model I have. But I've failed adapting any of the XML configuration files that I found online. And the console logs from the phone are not really helpful to a non-expert. #voip #cisco #sip
