Overview 2 H.323 Trunks

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
	network optimization by using the existing network resources.
H.323 Trunk	The TN802B IP Interface in Medpro mode enables H.323 trunk service using IP
	connectivity between two DEFINITY ECS systems. H.323 trunk groups can be
	configured as DEFINITY-specific tie trunks supporting ISDN trunk features such as
	DCS+ and QSIG, or as generic tie trunks permitting interconnection with other
	vendors’ H.323 v2-compliant switches, or as direct-inward-dial (DID) type of
	“public” trunk providing access to the switch for unregistered users. A variety of
	signaling options can be chosen by the system administrator.
IP Trunk	The IP Trunk mode (of the TN802B IP Interface) will typically be chosen for
	interoperability with existing TN802 (as opposed to the TN802B) IP Interface circuit
	packs. IP Trunk mode can be used only between two DEFINITY switches. Each IP
	Interface circuit pack in IP Trunk mode provides a basic twelve-port package that can
	be expanded up to a total of 30 ports.

IP Softphones

DEFINITY IP Softphones operate on a PC equipped with Microsoft Windows 95/98/NT and with TCP/IP connectivity to DEFINITY ECS. DEFINITY IP Solutions supports three IP Softphone configurations:

• Road-warrior application of IP Softphone — a PC running the DEFINITY IP Softphone application and an H.323v2-compliant audio application, with a single IP connection to a DEFINITY server.

• Telecommuter application of IP Softphone — a PC running the DEFINITY IP Softphone application with an IP connection to the DEFINITY server, and a standard telephone with a separate PSTN connection to the DEFINITY server.

• CentreVu IP Agent — same as the Dual-Connection IP Softphone with the addition of call-center agent features that enable agents to work at home.

The DEFINITY IP Softphone can also operate in a “native H.323” mode, which is a

PC-based single phone with limited features.

Documentation on how to set up and use the IP Softphones is included on the CD-ROM containing the IP Softphone software. The documentation includes a Getting Started quick reference, an overview and troubleshooting document, and context-sensitive help integrated with the softphone software.

Procedures for administering the DEFINITY ECS server to support IP Softphones are given in DEFINITY ECS R8.2 Administrator’s Guide , 555-233-506.
