I have configured 911 dial peers to route out FXO ports on my 1760 router. When I dial 911 the light on the FXO port briefly lights up for half a second then goes out. It then trys the next FXO port and the same thing happens. I then receive a busy signal.
I have verified that the POTS line is good by plugging in an analog phone and dialing out. I have also tried different IOS versions and swapped out the FXO card with new. Nother seems to help. If you have any advice please post. Thanks in advance.
Below is a copy of the debug vpm signal.

Do you have "forward-digits 3" on your dial peers? Can you post your config?

Brandon,
Thanks for replying. This has been becoming a hi-priority issue with the administration. Below is a copy of the 2 dial-peers I use for 911. 8 is our outside access code. I also attached a current copy of the running config on this router.

Can you dial any other number with the 8T dial peer? Can you dial 8911 which points directly to the 3/0 port?

NO...
In SRST mode, I receive a dial tone from the router. When I dial 8 the FXO port briefly lights up then the line goes dead. I cannot make ANY calls out this FXO port.

Under call-manager-fallback, remove the "access-code fxo 8" command.

I removed the access-code and placed a test call. The same thing occurs. I have opened a TAC case they want me to upgrade the IOS. I'm not very confident that will fix the problem.
