ISDN Connectivity problem

Hi,

I've setup a router to play with over ISDN, I'm using our pop router at the other end and all is well if I connect from that...

I.e. incoming connections to the router I'm playing with are fine.

I just can't make an outgoing call via ISDN.

Heres the config:

I've tried setting the line speed to 56k

i.e.

dialer map ip 111.111.111.1 speed 56 name ***** **********

but no joy....
 
We dont use them on any other routers and we have no problems?

 
SPIDS are only used to define channels for voice and data and we don't use voice so that would have no bearing (pardon the pun) on the problem.
 
My apologies, I'm in North America hence we need spids. It really has nothing to do with you using voice. See below

"Some service providers use service profile identifiers (SPIDs) to define the services subscribed to by the Integrated Services Digital Network (ISDN) device that is accessing the ISDN service provider. The service provider assigns the ISDN device one or more SPIDs when you first subscribe to the service. If you are using a service provider that requires SPIDs, your ISDN device cannot place or receive calls until it sends a valid assigned SPID to the service provider when accessing the switch to initialize the connection.

Currently, only the DMS-100 and NI-1 switch types require SPIDs. The AT&T 5ESS switch type may support a SPID, but you should contact your provider for information on what the SPID must be configured as. Remember that SPIDs are only required in North America and are configured only if required by your telco/provider."

Have you tried using the debug commands? Debug ppp authentication and debug ppp negotiation.
