No dial tone with VIC3-2FXS/DID on cisco 2901

Hi all,

I am trying to connect an analogue phone to my Cisco router through a VIC3-2FXS card plugged on slot 3. Router runs Version 15.4(3)M3, RELEASE SOFTWARE (fc2). 

I have tried a couple of different phones but I cannot get any dial tone.

Here my conf 

#sh run 
voice-port 0/3/0
 ring cadence pattern01
 cptone GB
 caller-id enable

dial-peer voice 1001 pots
 destination-pattern 1001
 fax rate disable
 port 0/3/0

 

#sh voice port sum
                                           IN       OUT
PORT            CH   SIG-TYPE   ADMIN OPER STATUS   STATUS   EC
=============== == ============ ===== ==== ======== ======== ==

0/3/1           --  fxs-ls      up    dorm on-hook  idle     y

 

Any idea?

 

Thank you very much

Hi,

Are you sure that the pin out on the phones match the FXS ports?

Hi Manish, 

many thanks for your reply

I checked the links provided. I am not using STCAPP. As you seen before, If I do show voice-port summary, I see the port in on-hook state. However, if i lift the receiver it doesn't change the state it remains in on-hook and there is no dial-tone; I've reinserted the voice module card in and swapped the slots without any joy. 

I also have a couple of IP phones (7821) connected on the router and they are both working ok.

This is the output of 
#sh voice dsp

 

 *DSP VOICE CHANNELS*

On the second link, how can I check on IOS if I have the feature IP Plus or Enterprise Plus?

Thank you

#show voice dsp group all

#show voice dsp error

 

enable the below debug and shut and no shut the port, go off-hook and see the behavior. if still same collect the debug post the same.

Br, Nadeem Please rate all useful post.

Hi all and thank you for you help

I've tried a couple of different RJ-11 cables working on other phones. The led on the back of the router doesn't lite up. 

Nadeem, i turned on debug you asked and sh+no sh the port + off hook but nothing comes up.

Here's the commands output for 

#sh voice dsp group all
#sh voice dsp  error
#sh diag
#sh ver

Thank you 

Hi Paolo.

Please look at the led near the port.

Does the led lite up when you go off hook?

Please post the output of a show diag and show ver.

Please provide also logs as Nadeem requested.

 

Thanks

 

 

Regards

Hi all,

I brought in a tester and I found out that I have +44V. I plugged in a adapter with pins splitter and I check pin by pin. Using an adaptor, going from RJ-11 to RJ-45 back to the analogue phone I have my dial tone and telephony is working ok. I'll make a suitable RJ-11 cable. 

Thank you guys for your help.
