We are currently testing a UC520-solution. Internally we can call without problems, but when we try to call out, we get a message: unknown number... .
I suppose it has something to do with the dialing plan, I am using the Cisco configuration assistant. And these settings are for a Belgian company.
The ISDN has a clip of 10 numbers, i suppose that i need to setup each phone with one of the numbers in this clip. Is this the full number with areacode?
It's hard to find, locally based specifications!
