TGM550 Is Installed But the VoIP Interface Is Unavailable

Problem—I installed the TGM550 Telephony Gateway Module and configured the VoIP interface—for example, vp-3/0/0—but the interface is not accessible. The show chassis hardware command displays the TGM550 installed on slot 3. However, the show interfaces terse command does not display the vp-3/0/0 interface, and the show interfaces vp-3/0/0 command displays an error:

error: device vp-3/0/0 not found

Solution—The VoIP interface might be unavailable because the TGM550 firmware version is not compatible with the JUNOS software version installed on the Services Router. For more information, see TGM550 Firmware Compatibility with JUNOS Software.

To correct the TGM550 firmware and JUNOS software version compatibility error:

1. Check the router's system log messages for a version incompatibility error similar to the following:

   Jan  5 11:07:03  host fwdd[2857]: TGMT: RE (1.0) - TGM (2.0) major protocol version mismatch: not marking TGM slot ready

2. If the error exists, connect to the TGM550 through the console port. (See Connecting Through the TGM550 Console Port.
3. To view the TGM550 firmware version, enter
   TGM550-003(super)# show image version

   Bank 	      Version
   ----------- -------
   A (current) 26.23.0
   B           26.22.0
   

   In this example, the current TGM550 firmware version is 26.23.0.

4. Refer to the Communication Manager Software & Firmware Compatibility Matrix at http://support.avaya.com to identify the JUNOS software version that is compatible with the current TGM550 firmware version.
5. Upgrade the router with the compatible JUNOS software version. For information about upgrading JUNOS software, see the J-series Services Router Administration Guide.
