Here is another problem from my make-shift lab. For DDR, I have no ISDN so
I am trying to use a 3620 w/ a 2fxs card to simulate telco so that I can
dial from 1 router to another via aux ports with identical 14.4 USR
sportsters.
When I send interesting traffic the call is initiated, the modems dial. I
hear them connect but the pings are not successful. I did a debug ppp nego
and got the following output below, the calling router sends ppp packets,
but the called router doesn't see them. The interface counters of both
routers never recieve any packets, but when making a call the calling router
will increment CRC input errors.
Bellow are the configs and debug output.
Voice router (3620)
voice-port 1/0/0
!
voice-port 1/0/1
!
!
dial-peer voice 111 pots
destination-pattern 111
port 1/0/0
!
dial-peer voice 112 pots
destination-pattern 112
port 1/0/1
