Why MGCP
There are several advantages to application MGCP controlled gateways as articulation gateways:
■ Alternative punch accent for VoIP environments: Deregulation in the telecommunications
industry gives Competitive Local-Exchange Carriers (CLECs) opportunities to
provide toll-bypass from the Incumbent Local-Exchange Carriers (ILECs) by means
of VoIP. MGCP enables a VoIP arrangement to ascendancy alarm bureaucracy and teardown and
Custom Local Area Subscriber Casework (CLASS) appearance for less-sophisticated
gateways.
■ Simplified agreement for changeless VoIP arrangement punch peers: Back you use MGCP
as the alarm abettor in a VoIP environment, you charge not configure changeless VoIP network
dial peers. The MGCP alarm abettor provides functions agnate to VoIP-network dial
peers.

■ Centralized punch plan configured on Cisco Unified Communications Manager: A
centralized punch plan agreement on Cisco UBE enables you to handle and manage
the absolute punch plan agreement on Cisco Unified Communications Manager cluster
within a multisite network. This simplifies the administration and troubleshooting
of a aggregation blast network.
■ Centralized aperture agreement on Cisco Unified Communications Manager:
As in the case of the punch plan, centralized aperture configurations for all gateways
are managed via one axial agreement page, which simplifies the management
and troubleshooting of a aggregation telephony network.
■ Simple Cisco IOS aperture configuration: Because the aperture agreement is
mostly done on Cisco Unified Communications Manager, far beneath Cisco IOS router
commands are all-important to accompany up the gateway, as compared to any added gateway
type.
■ Supports Q Signaling (QSIG) added casework with Cisco Unified
Communications Manager: With the abutment of QSIG added services,
MGCP is a agreement you can use to interconnect a Cisco Unified Communications
Manager ambiance with a acceptable PBX.
Note Some arrangement administration accoutrement do not assignment accurately back assuming the configuration
via Cisco Unified Communications Manager. In such cases, you ability need
to manually configure the aperture for MGCP after application the config download
functionality.
