Overview
8 channel Voice over Internet Protocol (VoIP) media gateway interface card that converts TDM voice to IP packets and vice versa.
Each channel can be assigned to support either:
- Samsung IP stations
- Samsung IP QSIG networking trunks for interconnecting whole systems
- SIP trunks
- H.323 trunks
When using the SMGI3 in Samsung IP QSIG mode, multiple telephone systems can be networked together in one large virtual system. Features supported across the network include central site shared voicemail with soft-key support, busy light status and roughly 95% feature transparency between systems.
The total number of channels that are supported per card can be expanded to 16 by adding the iDCS 8 Channel VoIP Daughter Board.
Channels on the SMGI3 are only in use when a connection is made between an IP device and a traditional TDM device. When two IP devices are communicating, no channels on the SMGI3 are in use.
