Hi JVR ,
I think you missed out dialer-group command on pri router.
Configure dialer-group under int dia 131.
Thanks,

Hi ,
there is no need of dailer-group in pri int.becoz some single bri lines are working on same confgiration.my main problem is why that router or NT Box automatically not dailing .

NO b channel basically means you have no channel to dial out as your simulator is set up incorrectly or your switch type is wrong.
what does "sh isdn status" show ? are you sure your really 5ess ? and not NI1 ?
Thx

Hello,
Verify your dialing numbers are correct as one of them looks kinda strange being 8 digits long. Also turn on chap/pap authentication.
Also what are your spid # ?
turn on debug dialer, debug isdn q931.
Thx Steve

Hi Shillyar,
that number is just i given for description,and next i turned on q931, then i found a error NO B-channel Found

try also doing a ping verses a test call as I have see calls flaged incorrectly with the 2 commands.
Thx
