Multi-Site Enterprise Management - Altienterprise Manager - Altigen AltiWare ACM 5.2 Administration Manual

Chapter 1: Overview
SIP Extension Home Gateway Assignment - This feature affects only multi-
•
chassis installations. The primary purpose of this feature is to allocate resources for
the IP phone when conferencing, silent monitoring, barging-in, and conversation
recording. This allows the administrator to configure sufficient VoIP resources in an
AltiGateway chassis for IP phone users assigned to this home AltiGateway.
SIP Trunk Support - An increasing number of service providers offer dial tone
•
through data network using SIP protocol. Beginning with Release 5.1, AltiWare
enables AltiGen's system to connect to IP-based trunking service providers via SIP.
SIP IP Phone (IP600, IP710, IP705) - Through firmware upgrade, all AltiGen IP
•
phones can run SIP protocols.
SIP NAT Traversal - This feature allows AltiWare to connect to a remote SIP phone
•
or IPTalk behind NAT without changing the NAT setting at the remote location.
Support for RFC 2833 (DTMF payload embedded with RTP) - Supported in SIP
•
trunks only. This feature helps to resolve DTMF tone detection and regeneration
when using G.723.1 or G.729 codec. Basically low bit rate compression will distort
DTMF tone during compression. The far end device may not be able to recognize the
DTMF digits. RFC 2833 specifies a separate RTP payload format to carry DTMF
information to ensure the other side can recognize the tone properly.
Support for both SIP and H.323 Tie Trunk - When setting up a system-to-system
•
VoIP tie trunk, either SIP or H.323 protocol can be used.

Multi-Site Enterprise Management - AltiEnterprise Manager

Replaces DINA Manager and IP Dialing Table in 5.0A
•
VoIP domain - When networking multiple AltiGen systems from different sites, one
•
system can be assigned as the VoIP domain controller to propagate configuration
data to member systems.
Directory Synchronization - When a new extension is added to one of the member
•
systems and configured as a Global extension, the VoIP domain controller will
propagate this extension to all member systems. Every member system within the
VoIP domain can see the extension number plan of the other systems.
Multi-site Call Routing - When a user dials an extension number which is not a
•
local extension number, the system searches the Domain extension list. If a list is
found, the system will dial the number by using the IP address and extension
number stored in the Domain extension list.
Domain User Management - VoIP domain controller can resolve the conflict if
•
duplicated extension numbers are created in different member systems. This feature
also manages extension relocation. When an extension user is relocated to another
member system, its voice mail and greeting can be relocated as well.
Global Least Cost Routing - When multiple systems are in different area codes or
•
countries, the administrator can set up Global Least Cost Routing to route long
distance or international calls through member systems. The routing rules are
propagated to all members automatically.
Global IP Dialing Table - In the 5.1 Release, the IP Dialing Table moved to
•
AltiEnterprise Manager. The IP Dialing Table configuration is used to create location-
based routing in the AltiEnterprise. Beginning with Release 5.1, the IP Dialing Table
supports hop-off blocking by location to prevent unnecessary hop-off calling.
