MGCP
MGCP is a client/server alarm ascendancy agreement congenital on a centralized ascendancy architecture.
MGCP offers the advantage of centralized aperture administering and provides for largely
scalable IP telephony solutions. All punch plan advice resides on a abstracted call
agent. The alarm agent, which controls the ports on the gateway, performs alarm control. An
MGCP aperture does media adaptation amid the PSTN and VoIP networks for external
calls. In a Cisco-based network, Communications Managers action as alarm agents.
MGCP is a plain-text agreement acclimated by call-control accessories to administer IP telephony gateways.
MGCP was authentic beneath RFC 2705, which was adapted by RFC 3660, and superseded
by RFC 3435, which was adapted by RFC 3661.
With MGCP, Cisco UCM knows of and controls alone articulation ports on an MGCP
gateway. This access allows complete ascendancy of a punch plan from Cisco UCM and gives
Communications Manager per-port ascendancy of access to the PSTN, bequest PBX,
voice-mail systems, and POTS phones. MGCP is implemented with use of a alternation of
plain-text commands beatific via User Datagram Agreement (UDP) anchorage 2427 amid the
Cisco UCM and a gateway.
It is important to agenda that for an MGCP alternation to booty abode with Cisco UCM, an
MGCP aperture charge accept Cisco UCM support. If you are a registered chump of the
Software Advisor, you can use this apparatus to accomplish abiding your belvedere and your Cisco IOS
software or Cisco Catalyst operating arrangement adaptation are accordant with Cisco UCM for
MGCP. Also, accomplish abiding your adaptation of Cisco UCM supports the gateway.
