If you connect your butt-set to these lines do they work?

Oh sorry Erick.

The hardware is a C2811 with 3 VIC2-4FXO cards utilizing 12 analog phone lines from the telco (AT&T).  I have 2 DSP modules (PVDM2-16 & 64) installed with a NM-CUE module installed as well.

All of the lines exhibit the same problem where people can dial to the office and the phone rings.  But outbound calls by that office do not work and display that same error I showed in the first e-mail.  I attempted to use the groundstart command on my voice ports per CCIEID1OT's recommendation, but that didn't work either.

Thanks for that call command.  Here is the output for outbound calls... I see the "no circuit 34" you mentioned!
15B7 : 347 246488340ms.346 +-1 +1260 pid:6 Originate 16152176245
 dur 00:00:00 tx:0/0 rx:0/0 22  (no circuit (34))
 Telephony 0/0/0 (347) [0/0/0] tx:0/0/0ms None noise:0dBm acom:0dBm
  long duration call detected:n long dur callduration :n/a timestamp:n/a

Also, here are the results from the test voice command you gave me:
005578: Jun 14 08:50:42.880 CDT:
Values read from SiLabs Codec connected to DSP 0, channel 8:
--------------------------------------------------------------
Register 29 = 0xD5

I noticed the Register 29 comes out with different values for different ports.  Such as 0x00, 0xD5 & 0xD4.

What are your recommendations since I get the "no circuit 34"?  The only thread I saw in regards to my initial error on Cisco's support forums is this: https://supportforums.cisco.com/message/3118805#3118805

However, the user ended up saying that the Telco was at fault and that's how he got it fixed.  I just wanted to make sure all my hardware was ok before tell AT&T because in the past, they always tell me to check my equipment first.

Thanks so much.

I would start by making sure each of the analog lines worked fine, with a regular old princess phone, if possible. Since it was working fine, and config hasn't changed, it's likely an issue with the phone lines or cabling.

You don't mention what type of hardware you have, but try reseating the cables, especially if you have a amphenol connector. Those tend to vibrate loose over time and cause problems like this, where calls fail but some work depending on what port is being used.

Output from 'show call history voice brief' may be useful. If the cause/reason states no circuit 34 then the line may be a problem.

If you have a ISR router, you can try this, but it varies with voice-card hardware, a 0x0 result indicates the router see's no voltage on whatever is attached to the voice-port.

term mon
test voice port x/y/z si-reg-read 29 1

Where x/y/z is your voice-port #/#/#, you need term mon to see the output from the test command.

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:
