The capital capacity covered in this affiliate are the following:
■ The Cisco Unified Communications System Architecture absolutely integrates communications
by enabling data, voice, and video to be transmitted over a distinct network
infrastructure application standards-based IP.
■ VoIP is the ancestors of technologies that allows IP networks to be acclimated for articulation applications,
such as telephony, articulation burning messaging, and teleconferencing.
■ VoIP uses H.323, MGCP, SIP, and SCCP alarm signaling and alarm ascendancy protocols.
■ Signaling agreement models accommodate peer-to-peer and client/server categories of
protocols.
■ Configuring articulation in a abstracts arrangement requires arrangement casework with low delay, minimal
jitter, and basal packet loss.
■ The absolute articulation conversations are transported beyond the manual media using
RTP and added RTP-related protocols.
■ Gateways affix IP Communications networks to acceptable telephony networks.
■ Several types of articulation gateways accommodated all kinds of chump needs, from baby enterprises
to ample account provider networks.
■ Supported Cisco IP telephony deployment models are distinct site, multisite with centralized
call processing, multisite with broadcast alarm processing, and clustering
over the IP WAN.
■ In the single-site deployment model, the Cisco UCM applications and the DSP
resources are at the aforementioned concrete location. The PSTN handles all alien calls.
■ The multisite centralized archetypal has a distinct call-processing agent. Applications and
DSP assets are centralized or distributed, and the IP WAN carries articulation traffic
and alarm ascendancy signaling amid sites.
■ The multisite broadcast archetypal has assorted absolute sites, anniversary with a callprocessing
agent, and the IP WAN carries articulation cartage amid sites but not call
control signaling.
■ Clustering over an IP WAN provides axial administration, a unified punch plan, feature
extension to all offices, and abutment for added alien phones during failover, but
places austere adjournment and bandwidth requirements on the WAN.
