Bad FXS card?

I don't claim to be a voice expert, but I can't get my VIC-2FXS to provide a dial tone to any of my analog phones. I've even tried the debug voip ccapi all (which shows you all calls, including any attempt to take a phone off hook).

My thinking is that even if my config isn't good, the FXS port should be able to at least provide a dial tone. Have tried to connect with both crossover and straight-through cables.

Anyone know any other debug or show commands that can help troubleshoot a possible bad FXS card? Running 12.4(T) on a 2691

when its plugged in you should get tone. Reading that you are on a 2691 do you have the voice module. I'm not sure if anything in the 2600 series could use the voice cards without the voice module.

Do you have the VIC-2FXS installed in an NM-1V or NM-2V?

Do you see the voice ports in the configuration and when you do a show version command?

Do you see the VIC-2FXS when you do a show diag?

Do you have an AIM-ATM installed?

Netwurk

It's in a NM-2V paired with a VIC-2FXO

You can see it in show ver and show diag

No AIM-ATM is installed, it does have an AIM-VPN which shouldn't affect voice as far as I know

What is your configuration?

The VIC-2FXS should accept an RJ-11 plug -- and the cable is just a regular phone cable.

What does the output of a show voice summary give you?

What does the output of a show voice port give you (for the port you're plugged in)?

What does show voice call summary give you?

Does anything change when you go off hook (lift up the phone handset)?

What IOS feature set and version are you using.

Going off hook generates nothing when debugging (unless I take one of my 7940's off hook, then I get tons of code).

Will try to put together the relevant parts of the config when I have a chance. I have CME running, so the config is huge

mrblackmamba343

can I see a "show run" of the routers config

Netwurk

Opened the thread to see if I forgot any show or debug commands to troubleshoot the card.

No sense posting the whole config as I doubt it's a config issue. I'm going to try to get myself a known good card to test with. Thanks everybody.

hey mate,

Quite possible your FXS card is dead....

I finally received my 2 x VIC-2FXS today and NM-2V.... got dial tone straight away with no config on the voice ports...

All I've done is create my pots dial-peers and my voip dial peers... necessary to make actual calls.

Yeah I think you are right that the card's DOA

I waited too long to test it or I might have been able to do something with the 30-day warranty

But the router rocks as a CME and all my IP Phones play nicely with it so I think I did OK

APA

you should get into the habit of testing bits of hardware as soon as you get it!!! Saves you from the problem you're having now, especially if you get another DOA piece.

We spend so much on this stuff!!! Worth the time and effort

Agree with you there. I thought I had tested everything the day I got it. But I neglected to plug in an analog phone until this week. Oh well. Live and learn.

Netwurk

UPDATE: Finally got another FXS card and like APA said, you can plug a phone in and get a dial tone right away. Glad that solved it, since some of the troubleshooting guides from Cisco made me think I might have a bad NM-2V.

Popped in this config:

dial-peer voice 100 pots
destination-pattern 1234
port 1/0/0

And then I could call my IP Phones, so all is good.

Fish!

I have had horrible luck with Cisco FXS ports being bad. In fact just today I received an eBay VIC-2FXS with one bad port. I have an IAD2432 in my lab rack and of its 24 FXS ports only 10 really work. another 8 or so have HORRIBLE line noise, and the balance show perpetually off-hook in show voice port summary, no dial-tone at all.

An FXS port with default config should give a nice clean dial tone. Anything else is bad hardware (or incompatible! Always check your show diag).
