I've made some progress, and guess the correct isdn switch type.

Now, this is what I'm getting after a single ping. It looks like it's
telling me "Mandatory IE missing".

Could someone please take a look.

Thanks

Albert

Abert,

Try to include your SPID1 and SPID2 under the interface configuration since
your are using basic-ni switch type. For example:

int bri 0
isdn spid1 0835866101 8358661
isdn spid2 0835866301 8358663

Hope this help.

Hello group,

I'm having a little problem with an isdn config. Basically, it's not dialing
through when I try to ping the other side. I'm sure the dialer map is
working, and my suspicion is that the isdn simulator (emutel lite) could be
misconfigured.

I have included my config, the "show isdn status" and "debug isdn q931"
output for reference.

Thanks in advance,

Albert
