Hi guys,

I am using cisco 2921 router with :"c2900-universalk9-mz.SPA.155-3.M4a.bin" image. i have connected  VIC2-2FXO  to the router. 

before shut that port Oper state was dorm, after no shut, it always showing DOWN state.please help me.

when i trying to call from my mobile number to that particular (DID Number on FXO)call not hitting my MGCP gateway

i used these debug commands:

debug vpm all

debug vtsp all

Router#show voice port summary
IN OUT
PORT CH SIG-TYPE ADMIN OPER STATUS STATUS EC
=============== == ============ ===== ==== ======== ======== ==

Are you sure the signaling is GroundStart not LoopStart?

Have you tried replacing the cable or swapping the tip and ring wires?

[Nisar kizhakkepatt]

Yes, I am sure. I swapped cable, swapped and replaced FXO module. till call not detecting 2921 gateway.

still fxo operation state is down after shutdown the voice port

Can you provide "sh run", "sh diag" and "sh voice-port 0/1/0"

[Nisar kizhakkepatt]

Okey definetly..

when i trying shut and no shut command. some output is getting like this,

Router(config-voiceport)#shutdown
Router(config-voiceport)#
*Nov 22 16:36:25.839: htsp_process_event: [0/1/1, S_OPEN_PEND, E_HTSP_IF_OOS]
*Nov 22 16:36:25.839: %LINK-3-UPDOWN: Interface Foreign Exchange Office 0/1/1, changed state to Administrative Shutdown

Router(config-voiceport)#no shutdown
Router(config-voiceport)#

What is the port showing as in CUCM? Is it registered?

Is it configured with correct port on CUCM?

[Nisar kizhakkepatt]

yeah, showing Registered. port is currect 0/1/1

when dial to particular port after connecting an analog phone. it was ringing

Hi chris, 

are you there,

[Chris Deren]

Sorry, I got busy at work.

One thing I would try because I've stopped trusting MGCP years ago for issues like these is to reboot the gateway as you would be surprised how often that solves MGCP related issues. If that does not work I would remove the MGCP control of this port to see if port status changes to correct state.
