ISDN PRI E1 Cannot make outgoing calls to remote sites

I am trying to configure a 2610 Pri ISDN2 E1 to dial out to our remote sites. I have managed to configure the router so that remote sites can call in, but not out. Not much use when I need to manage the remote routers! Shiva Access Ports are used at the remote sites. Can anybody send me an example configuration or give any idea where I am going wrong. Any informtion would be much appreciated.

Mark,

Please show your config and the "debug dialer events" and "debug isdn q931" output when you are attempting to dial out.

Re: ISDN PRI E1 Cannot make outgoing calls to remote sites

First you need to make sure that the E1/PRI line is in sync with telco switch on layer 1 and 2..For that following link will help you.

Once you have verified that layer 2 status is "Multile_Frame_Established" you need to turn on following debug and call in the 2600 router

debug isdn q931

debug ppp nego

debug ppp authentication

term mon

debug isdn q931 will inform you that the call is received/sent from the telco switch or not. Here is the url for more on that..

Post the debug with running config as well.
