Also, make sure your version of Cisco UCM supports the gateway. VoIP defines a way to carry voice calls over an IP network, including the digitization and packetization of the voice streams.

SIP defines end-to-end call signaling between devices. Starting with simple media convergence, these advantages evolved to include call-switching intelligence and the total user experience. A voice codec is responsible for the conversion of your analog voice stream into a digital packet. Cisco Unified Communications Architecture The Cisco Unified Communications System fully integrates communications by enabling data, voice, and video to be transmitted over a single network infrastructure using standards-based IP.

RAS is used to perform registration, admission control, bandwidth changes, status, and disengage procedures between endpoints and gatekeepers. As bandwidth has increased, so has the demand for VoIP systems.

Cisco Conference Connection and Cisco Unified MeetingPlace enhance the virtual meeting environment with an integrated set of IP-based tools for voice, video, and web conferencing. This approach results in bandwidth being unused when no voice traffic exists.

SIP is a text-based protocol that borrows many elements of HTTP, using the same transaction request and response model and similar header and response codes.

The call agent, which controls the ports on the gateway, performs call control. When multiple paths exist to connect a call to its destination, some of these paths might be preferred over others based on cost, distance, quality, partner handoffs, traffic load, or various other considerations.
