Multi-Service Business Gateway (MSBG)

Overview

Multi-Service Business Gateway (MSBG) is the name given to Sangoma's SBC product that incorporates a PRI Gateway, all-in-one.
Now as well as SIP, TDM connections can also be terminated on SBCs.

• TDM PBXs

• PSTN trunks

Open

If you wish to convert a Sangoma SBC into an MSBG, simply install a Sangoma TDM Card (i.e. a101/102/a104) into the SBC appliance.
The software will automatically detect the Sangoma card and expose the PRI gateway and create basic routing functions. 
(SBC software 2.2 and higher is required to convert your SBC into an MSBG)
