MTP Types
Two types of MTPs are accurate on Cisco VoIP accessories (for example, Cisco IOS
routers and Cisco Unified Communications servers): software MTPs and accouterments MTPs.
Software MTP
A software MTP is a ability that can be implemented by installing the Cisco IP Voice
Media Streaming Appliance on a Cisco Unified Communications Manager server or by
using a Cisco IOS aperture after appliance DSP resources. A software MTP accessory supports
G.711 to G.711 and G.729 to G.729 streams. A Cisco IOS-enhanced software
device can be implemented on a Cisco IOS router by configuring a software-only MTP
under a DSP farm. This DSP acreage can be acclimated alone as a authentic MTP and does not require
any accouterments DSPs on the router. Examples are as follows:
■ Cisco IP Voice Media Streaming Application: This software MTP is a accessory that is
implemented by installing the Cisco IP Voice Media Streaming Appliance on a
server. When the installed appliance is configured as an MTP application, it registers
with a Cisco Unified Communications Manager bulge and informs Cisco Unified
Communications Manager of how abounding MTP assets it supports. The IP Voice
Media Streaming Appliance is a ability that ability additionally be acclimated for several functions,
and able architecture charge accede all functions together.
■ Cisco IOS based: This MTP allows agreement of any of the afterward codecs,
but alone one ability be configured at a accustomed time: G.711 mu-law and a-law, G.729a,
G.729, G.729ab, G.729b, GSM, and pass-through. However, some of these are not
pertinent to a Cisco Unified Communications Manager implementation.
The router agreement permits up to 500 alone streams, which abutment 250
transcoded sessions. This cardinal of G.711 streams generates 5 Mbps of traffic.
