This chapter describes how to set up and perform initial administration of IP Trunks between 
DEFINITY ECS switches and between DEFINITY and non-DEFINITY switches that support the 
H.323 V2 signaling protocols. The IP trunk connections described in this chapter use the TN802B 
circuit pack in the MEDPRO mode. See Appendix F for administration of trunk connections that 
use the TN802 or TN802B in the IP...

IP-Connected Trunks
IP-connected trunks allow trunk groups to be defined as ISDN-PRI-equivalent tie 
lines between switches over an IP network.
Trunks using IP connectivity provide cost-reduction and simplified management. 
Benefits include a reduction in long distance voice and fax expenses, facilitation of 
global communications, full-function networks with data and voice convergence, and...

H.323 Trunk Administration
This section describes the administration steps needed to setup H.323 trunks. The first subsection covers the 
enabling administration that needs to be in place before the trunk administration can be done. The second 
subsection gives a summary of the H.323 trunk administration and the last subsection gives the detailed steps.

You can also use the Audio IP port number range field to specify a block of port 
numbers to be used for audio connections. Then, if your network is equipped with the 
appropriate data filtering devices, audio data can be segregated from other data traffic 
to improve quality of service.
Open the screen with the change command (ch ip-p) and set the following fields:
