Hi John, Two things I've noticed.
If you use basic-ni as the ISDN switch, you should configure your 'isdn spid' statement as follows. Note that you include the LDN (local dial number) in the SPID with no area code: On router #1: isdn spid1 60255513131111 5551313 On router #2: isdn spid1 60255512121111 5551212 ALSO... *don't* configure 'isdn spid1' on router #1 and 'isdn spid2' on router #2. Instead, configure 'isdn spid1' on BOTH routers. Both routers should then pick up the relevant TEI from the ISDN switch. 'spid2' is only valid if you've already defined 'spid1' on the unit. I've been successful doing this a number of times. Let me know how it works. Paul ""John Hardman"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hi All... > > I have a question...
