Sample text

323 clients, such as video terminals. Connections can be configured between devices using static destination IP addresses. 323 gateways are not registered with Cisco Unified Communications Manager as an endpoint is. 323 device. MGCP MGCP is a client/server call control protocol built on a centralized control architecture. MGCP offers the advantage of centralized gateway administration and provides for largely scalable IP telephony solutions. All dial plan information resides on a separate call agent.

323 gatekeeper. 225 Registration, Admission, and Status: Registration, admission, and status (RAS) is the protocol between endpoints (terminals and gateways) and gatekeepers. RAS is used to perform registration, admission control, bandwidth changes, status, and disengage procedures between endpoints and gatekeepers. A RAS channel is used to exchange RAS messages. This signaling channel is opened between an endpoint and a gatekeeper prior to the establishment of any other channels. 323 endpoint.

Implement the recommended network infrastructure for high availability, connectivity options for phones (in-line power), QoS mechanisms, and security. Multisite WAN with Centralized Call-Processing Deployment The model for a multisite WAN deployment with centralized call processing consists of a single call-processing agent cluster that provides services for multiple remote sites and uses the IP WAN to transport Cisco Unified Communications traffic between sites. The IP WAN also carries call control signaling between central and remote sites.
