Background Information

The WS-X6624-FXS provides 24 FXS ports for analog phones, conference room speaker phones, and fax machines. The FXS module provides legacy analog devices with connectivity into the IP network. This connectivity enables the devices to utilize the IP network infrastructure for toll-bypass applications. The connectivity also enables the devices to communicate with other devices, such as IP phones and H.323 end stations.

For complete information, refer to Catalyst 6000 Family FXS Analog Interface Module.

Note: Cisco has announced the End-of-Sale and End-of-Life for Cisco Catalyst 6000 24-Port FXS Analog Module.

Cisco Communication Media Module (CMM) is the next generation of voice gateways and services module for Cisco Catalyst 6500 series switches and Cisco 7600 series routers. Cisco CMM is a modular line card that provides greater flexibility, better performance, and more density in a single Catalyst 6500 slot.

Configuration

• In order to configure a VoIP network with Catalyst 6000 switches, refer to Configuring a Voice-Over-IP Network.

• For WS-X6624-FXS installation, refer to Catalyst 6000 Family 24-Port FXS Analog Interface Module Installation Note.

• In order to configure a WS-X6624 FXS blade with Cisco CallManager 3.x, refer to Configuring the Catalyst 6000/6500 WS-X6624 FXS Blade with Cisco CallManager 3.0. The WS-X6624 FXS blade receives configuration via TFTP. The WS-X6624-FXS uses SCCP (3.0)/MGCP (3.1, 3.2, 3.3) in order to communicate with the Cisco CallManager server for the setup and teardown of calls.

• For fax configuration on a Cisco WS-X6624 with an H.323 gateway, refer to Fax Configuration on a Cisco WS-X6624 with an H.323 Gateway.

Known Issues

• On the WS-X6624-FXS analog interface module, the show spantree command displays the port status as not-connected. This error does not affect operation. The problem is resolved in CatOS 7.3(1). For more information, refer to Cisco bug ID CSCds00575 (registered customers only) .

• The WS-X6624-FXS analog voice module fails to come online and register with Cisco CallManager when you use Supervisor Engine CatOS 7.2(2). This problem is resolved in CatOS 7.3(1). For more information, refer to Cisco bug ID CSCdx30559 (registered customers only) .

• Voice modules, such as a WS-X6624-FXS and a WS-X6608-T1/E1, fail to register with Cisco CallManager if you use a WS-X6148-GE-TX for the CallManager connection. Use another type of module, such as a WS-X6148-RJ45V, for the Cisco CallManager connection. This problem is resolved in Cisco CallManager Version 3.3(3)sr1. For more information, refer to Cisco bug ID CSCeb38168 (registered customers only) .

• If you issue the show port command on a switch with voice modules, such as WS-X6624-FXS and WS-X6608-T1, the show port command appears to hang. Also, port information for the voice module does not print. And, at times, the digital signal processor (DSP) on the voice module can reset. This problem is resolved in CatOS 8.3(3). For more information, refer to Cisco bug ID CSCec01126 (registered customers only) .
