The Cisco High-Density Analog and Digital Extension Module for Voice and Fax (EVM-HD) is an industry-leading voice and fax interface module for Cisco 2821, 2851, 2901, 2911, 2921, 2951, 3825, 3845, 3925, 3925E, 3945 and 3945E Integrated Services Routers. It helps enable packet voice technologies with support for voice over IP (VoIP), including H.323, Media Gateway Control Protocol (MGCP) and Session Initiation Protocol (SIP).

The Cisco High-Density Extension Module allows Cisco 2821, 2851, 2901, 2911, 2921, 2951, 3825, 3845, 3925, 3925E, 3945 and 3945E Integrated Services Routers to connect directly to the PSTN and existing telephony equipment (for example, private branch exchange (PBX), Key system, analog telephones, and analog fax machines) through standard analog (FXS, DID, and FXO) and digital (BRI) interfaces.

The High-Density Extension Module supports telephony toll bypass, new packet telephony applications, and full gateway integration. With support for up to 24 total voice and fax sessions, the Cisco High-Density Extension Module is ideal for networks with high analog and BRI call-capacity requirements.

Adding expansion modules to the Cisco High-Density Extension Module baseboard increases voice and fax session capacity. The modular design of the Cisco High-Density Extension Module provides maximum flexibility-plug in up to two expansion modules in any combination to build the Cisco High-Density Extension Module best suited for specific packet telephony network locations.
