I have a Cisco 7940 phone which I have been told dont play well with SIP. I had it working well with 2talk but after a few months of non use (and in that time I went to 2talk plus and a fiber connection) I plugged it in to use it again, still with 2talk.
I now get a very annoying cut out every few seconds during a call.
To rule out 2talk as the culprit, does anyone feel like letting me try it out with their account breifly, which should not be a 2talk account.
PM me if you can help.
