I have a router (RouterB) that is not receiving LCP CONFACK messages from the sending router (RouterA). RouterB is sending a CONFREQ, RouterA is receiving it and sending a CONFACK to RouterB, but B never gets it. It is not getting any inbound messages for that matter. I had the provider test the T1 and it runs clean. Serial ports on both sides are up.
Not sure where to look next. Any suggestions?
