Uk isdn30 new setup problem

Asterisk Asterisk Support
1

Hi

At long last I have had BT install our new isdn 30 (I421) line for our asterisk server. 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.

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 new stack
– Executing GotoIf(“SIP/602-9989”, “0?5”) in new stack
– Executing Set(“SIP/602-9989”, “GROUP(602)=OUTBOUND_GROUP”) in new stack

FOR each channel and then

Can anyone help as have I missed somthing simple.
Thanks

Hi

It looks as your confs are all wrong.

what is span 2 as well?

This should get you on your way.

any further problems I can assist on site or remote and do hold ISDN simulators to test both * and the BT circuit to confirm that they are working correctly

Hi,

Thanks for your config example.

Found my problem, Bt installed the line yesterday but did not tell me I had to ring Bt to have it Activated.

Its now activated and works Great on UK isdn30e

Thanks for the help.
