Detailed Description

VoIP Gateway --2 FXS ports & 2 FXO ports
Supports :
peer-to-peer IP calls,
dial plan and caller ID
router function

The VOIP-G200 is mixed gateway of 2-line FXO and 2-line FXS with compact-size and high-performance. The two lines can be configured as different phone numbers or used as a relay gateway.


With integrated SIP protocol, it can forward the caller ID from exterior lines, which is an important function of PBX application. Its highly-reliable line detection function can avoid line down failure at maximum degree. And the superior echo cancellation algorithm and balanced circuit design can reduce the echo to the lowest.


Offering high-quality voice and stable performance, it is an ideal low-cost solution for PBX vendors, call centers and system integrators.
