'Unknown Number' showing for incoming calls

Hi all

Im a newbie when it comes to all this phone gubbins so forgive my lameness..

We've got a UC520 running CME connected to our ISDN via a BRI connection. All working great. Apart from.. when i call into the office from my mobile, I get Unknown Number appearing on my 7941.

In short, how do I get the calling nuber displayed on the phones rather than the cryptic Unknown Number?

Cheers

You might want to also check with your provider to find out if they support callerid or if you are set up to have it on your circuit.

Number should appear without any special command. Please send output of "debug isdn q931" taken with "term mon" first.

Well it seems that BT haven't enabled CLIP on our circuit so thats why we arn't getting any caller id's!

Thanks

Looking at the debug, the calling number is not present only the called number... BT needs to fix it.

hmm.. not sure where to go now.. theres some posts saying that the number may well be chopped off by the telco.. your going with BT being at fault mate?
