Cisco Unified Communications Manager uses a DSP farm to mix voice streams from multiple participants into a single conference-call stream. In an IP telephony network using Cisco Unified Communications Manager, the Conferencing and Transcoding for Voice Gateway Routers feature provides the conference-bridging service. Conference services, however, require a network-based conference bridge. In contrast, IP phones normally send voice signals directly between phones, without the need to go through a central device. Conference services are provided within this central device. In a traditional circuit-switched voice network, all voice traffic passes through a central device such as a PBX. Voice conferencing involves adding several parties to a phone conversation. Supports 2 channel groups per port.Ĩ-port clear channel data and voice T1/E1 module.
