IDM DP2000 Audio Access Gateway
IDM DP2000 Audio Access Gateway
I Overview
The IDM DP2000 Audio Access Gateway provides audio-to-SIP conversion, rack-mounted, supporting no fewer than 8 audio interfaces per unit. Each device is equipped with 1 Ethernet port and 1 serial debugging port, with a default configuration of 2 audio interfaces. It interfaces with conference room mixing consoles, audio matrices, amplification systems, and microphones. The device supports dual registration, SIP protocol, G.711, G.723, and G.729 voice codecs, T.30 and T.38 fax, QOS echo suppression, and WEB-based management.
