Introduction

This document helps you troubleshoot and explains the steps to find detailed information for the Cisco Voice Interworking Service Module (VISM) Media Gateway Control Protocol (MGCP) endpoint on a Call Control Cisco PGW 2200 solution. It helps you find Cisco VISM information and correlate the digital signal processor (DSP) and MGCP endpoint connection.

Prerequisites

Requirements

Readers of this document should have knowledge of these topics:

Components Used

The information in this document is based on these software and hardware versions:

  • Cisco PGW 2200 Software Releases 9.3(2) and 9.4(1)

  • Cisco VISM release 003.001.002.000

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

VISM MGCP Endpoints

Run a Cisco Snooper to display MGCP endpoint details. These details display SS7 IAM messages that include calling and called numbers and are linked to an MGCP endpoint. In this case, the CalledPartyNumber=92169679F and the CallingPartyNumber =9678. These are linked to MGCP endpoint vism/e1-1/31 via the MGCP Create Connection (CRCX ).

Issue the cc command to connect to VISM card 2. The cc command changes the card that you are currently logged into. Issue the cc command to change to the card that you would like to debug. If you would like to debug the control card, you do not need to execute the cc command since you are logged into the control card by default.

To find out the endpoint details and correlate this with the Cisco Snooper details, issue the dspxgcpcons command. This command provides the xGCP Connection ID information. If you you forget the command, issue the help command in combination with a list of available debug commands. For example:

8850bru2.1.2.VISM8.a > help dsp

This is example output of the dspxgcpcons command.

8850bru2.1.2.VISM8.a > dspxgcpcons

In this scenario, MGCP endpoint vism/E1-1/31 is linked to MGCP Connection ID = d7. Run the command dspxgcpcon d7 2 to display the attributes associated with a call agent established connection. This command gives you details about the Local/Remote RTP port, the remote IP address, and the connection mode .

The dspm_endpt_info ShellConn command provides details on the MGCP endpoint that concerns the DSP number, DSP channel, the status, the transmit (TX)/receive (RX) tone, voice activity detection (VAD), and so forth. This command also provides detailed information on the previous codec. Alternatively, you can run the dspm_active ShellConn command which provides basic details for the connection and endpoint index.
