IP Resources Attributes

Overview

You can assign attributes to a VoIP module during initial configuration by using the Resource Attribute Configure message.

You can assign attributes during call set-up by using the Route Control or Outseize Control messages with Address Information Blocks (AIBs).

You can dynamically assign some attributes to a channel after call setup by using the Resource Attribute Configure message with the span/channel AIB.

Synchronizing VoIP Media Parameters

If you change VoIP resource configuration with the Resource Attribute Configure message, the local copy of the configuration maintained by SIP and H.323 software remains unchanged. You must resynchronize the configurations as follows:

• CSA users select the Resynchronization option.

• Non-CSA users send the Resynchronize VoIP Media Parameters TLV (0x0284) in the VoIP Protocol Configure (0x00EE) message. Refer to the 0x0284 Resynchronize VoIP Media Parameter in the API Reference for the details of this TLV.

Voice over Internet Protocol. The delivery of voice information in digital form in discrete packets rather than in the traditional circuit-committed protocols of the public-switched telephone network (PSTN).
Outgoing call setup during real-time call processing on a specific channel.
See Address Information Block.
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.
See Converged Services Administrator.
Tag-Length-Value block. A standardized block that allows data to inserted in a standard way into API messages.
Internet Protocol. Part of the TCP/IP family of protocols used to route messages and tracks the addresses of nodes.
A device that translates calls between an IP network and another network, typically the PSTN.
The point in the Excel platform where a DS0 connects to a network. Also known as a "socket."
Real-Time Transport Control Protocol.
Real-Time Transport Protocol. Supports transport of real-time data like interactive voice and video over packet-switched networks.
