[cisco-voip] FXO Outbound Call Not Working

Fri Jun 11 15:43:36 EDT 2010

I have a router that I've utilizes FXO modules for making calls.  When I first set it up, everything worked fine.  A few months later, users started reporting to me an intermittent problem for outbound calls.  Sometimes they can make calls, but the majority of the time, they get a fast busy signal.  I compared the current router's configuration to when I originally saved the configuration from initial setup.  Nothing changed.  Out of perhaps 10 calls made, maybe 1 of them went through.

The following is the config for a voice-port.  All the other ones have the same config.  2857 is the number to the Unity Express.
voice-port 0/0/0
 trunk-group POTS-FXO
 connection plar opx 2857
caller-id enable

I did try "no supervisory disconnect signal" but that didn't work either.

I turned on debugging for "vpm signal" and made several calls to different phone numbers.  The following output is just an example of what the result is for all calls:
