It appears that the debug is indicating correct information. Specifically, this message here: > 06:26:47: Cause 13, Diag 67 (Not obtainable/Invalid destination > address) The debug goes on further to be more specific: > Serial0: X25 O P7 CLEAR REQUEST (5) 8 lci 1024 cause 13 diag 67 Cannot route call So you are wondering which call and why? That is here: > From(7): 1115555 To(7): 4115555 So, where's the problem in the config, and why does the call not get routed? I went to your routing statements and your mapping statements for inconsistencies. Here is what I found: > x25 route 11155555 interface Serial0 > x25 route 21155555 interface Serial1 > x25 route 31155555 interface Serial2 > x25 route 41155555 interface Serial3 Subject: Re: X25 Lab [7:14915] > > I am having a problem with setting up an X25 Lab.
