0x27B0 RTP Payload Type

Use this TLV in the NPDI Universal ICB (0x0033) to configure the RTP Payload Type.

Used in:
0x0033 NPDI Universal ICB in:
Request for Service with Data message
Route Control message
Outseize Control message

Important! Do not confuse this TLV with 0x0100, which is the regular resource attribute TLV for RTP Payload Type. TLV 0x27B0 is the RTP Payload Type in NPDI format.

Tag-Length-Value block. A standardized block that allows data to inserted in a standard way into API messages.
Network Protocol Data Intelligence. Also called “Interworking,” it is a software product that operates within Excel’s Call Control (Layer 4) and Services (Layer 5) call processing layers. NPDI is meant to enhance Excel’s call processing product offering by allowing call processing layers (specifically Layers 4 and 5) to perform advanced analysis, generation, and conversion of Network Signaling (NS) Layer 3 information.
See Information Control Block.
Real-Time Transport Protocol. Supports transport of real-time data like interactive voice and video over packet-switched networks.
Outgoing call setup during real-time call processing on a specific channel.
Internet Protocol. Part of the TCP/IP family of protocols used to route messages and tracks the addresses of nodes.
PCM and companding standard used in Europe to compress and expand the amplitude range of a signal before and after transmission. See µ-Law.
PCM and companding standard used in North America and Japan to compress and expand the amplitude range of a signal before and after transmission. See A-Law
Session-Initiation Protocol. A signaling protocol used for establishing sessions in an IP network. A session could be a simple, two-way telephone call, or it could be a collaborative multi-media conference session.
ITU-T standard defines a set of call control, channel setup, and codec specifications for transmitting real-time voice and video over networks that do not offer guaranteed service or quality of service.
