[asterisk-users] isdn30 uk setup problem

[Nicholas Colyer]

Hi

 Can anyone help with my following problem connecting asterisk to a new 
provisioned isdn30e line.


At long last I have had BT install our new isdn 30 (I421) line for our 
asterisk server after 3 months of waiting.
Before this we have used asterisk with a tdm400 and some analogue lines.

I have installed a digium TDM 205 e1 card with port 1 connected to the 
isdn30 box via a rj45 network lead. (wired like a normal patch lead NOT 
crossover). Is this correct ?. I have no red warning lights just green ok 
lights.

Asterisk,libpri and zaptel are the latest ones from asterisk.org.

On trying to dial using the isdn30 im getting the following error 
Circuit/Channel congestion

-- Executing Set("SIP/602-9989", "GROUP(901392275533)=OUTBOUND_GROUP") in
