Overview
Depending on the model, the Media Gateway can be configured for the following operating mode:
•

Phone Emulating

1.1.1 Phone Emulating
In the Phone Emulating mode, the Media Gateway operates as a telephony gateway appliance that
emulates:
• up to eight station sets (DMG1000 models)
up to 24 station sets (single T1 DMG2000 model)
•
• up to 48 station sets (dual T1 DMG2000 model)
• up to 96 station sets (quad T1 DMG2000 model)
• up to 30 station sets (single E1 DMG2000 model)
• up to 60 station sets (dual E1 DMG2000 model)
up to 120 station sets (quad E1 DMG2000 model)
•
for transporting PBX functionality over a packet-switched network.
The Media Gateway translates protocols for call setup and release between the IP network and the
PBX or PSTN, and converts the media formats between the two networks.
Figure 1 shows how the Media Gateway provides a gateway between voice over IP (VoIP) devices
(H.323 or SIP) on a LAN and the PBX. By emulating station sets to the proprietary PBX, the
Media Gateway provides full call party information to the IP network.
Note: H.323 is only supported in Version 5.1 SU1 Software or earlier.
The DMG2000 or the analog version (DMG1008LS, DMG1004LS) of the DMG1000 can also
connect directly to the PSTN, as shown in Figure 2.
