AltiGen comm ACM 5.1 manual Multi-Site Enterprise Management AltiEnterprise Manager

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. Release 5.1 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 allow 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 - The IP Dialing Table is moved to AltiEnterprise Manager. The IP Dialing Table configuration is used to create location-based routing in the AltiEnterprise. The 5.1 IP Dialing Table supports hop-off blocking by location to prevent unnecessary hop-off calling.
