Cisco EM-HDA-4FXO High-Density Analog Voice/Fax Network Module Expansion

Cisco 2600 and 3600 high-density analog voice/fax network modules provide enterprises, managed service providers and service providers the ability to directly connect the PSTN and legacy telephony equipment to existing Cisco 2600 and Cisco 3600 routers. This provides immediate multiservice advantages, such as telephony toll bypass, new packet telephony applications, and full gateway integration within a Cisco AVVID (Architecture for Voice Video and Integrated Data) IP telephony architecture.
