Hello All,
Just to share my experience troubleshooting an analog E&M config to an Alcatel
PBX.
Took me 3 months of back and forth with Cisco TAC(not everyday on the case..) b
ut eventually solved
the problem.
The issue was we were not sure which was the E&M and T/R pairs. Finally nailed
the E&M ports and T/R
pairs but still not working. Tried all the signalling methods - delay , immedia
te, wink-start but no
success. Then noticed that the h/w was sometimes seizing the line and DORMANT->
UP but not
consistent. Finally nailed it as requiring a complete reboot to have the new ch
anges take effect! I
was using 12.07T. Shut/No shut wasn't enough. I probably got the correct physic
al wiring many times
over but just didn't know it as I should also have rebooted the router!
Anyway, hope this helps those in similar situations. Maybe it's fixed in later
IOS versions?
Regards,
Andy.
