After adding a new phone and extension to our CallManager system, you are able to call out just fine but can?t call the extension at all. When you try to call this extension, you get a fast busy.
Everything is set up correctly for this phone and extension. Have tried different extensions, same result. If you add a shared line to the phone, the shared line will ring when someone calls that extension.
Have tried different phones as well. Originally we were using a 7941, now we are using a 7940.
What would cause this?
