The KE1GW-640 board combines the flexibility of voice resources for T1/E1 links and the functionality of the TDM/SIP gateway for PSTN and VoIP calls, resulting in an excellent choice for CTI applications using T1/E1 links and voice connection through Ethernet IP. The KE1GW-640 is ideal for call distribution applications for IP call centers, interconnecting voice among Ethernet servers, and other CTI applications needing VoIP integration. The KE1GW-640 can also establish up to 30 calls using T1/E1 link, and simultaneously, an additional 34 calls using SIP terminals connected by network IP.

Using the conference resource, T1/E1 calls can be connected to IP calls individually, or in groups. With the recording resource, calls between the T1/E1 and IP channels can be recorded in full duplex mode. The KE1GW-640 also has 30 voice resources implemented by the board's DSPs making it the perfect board for a variety of CTI applications. 

Khomp offers the KE1GW-640 in two models; PCI and PCI-Express. The PCI-Express model has DMA technology, which reduces CPU consumption, allowing increased density per server.
