The EBS-E1 family with SIP channels is designed to add high availability to the robust CTI solutions with an IP network.

Maintaining the standard and quality of the Khomp family of boards, the EBS-E1 VoIP performs all of the audio and signaling processing within its own hardware. Its voice resources, which include detection of voice mail, detection and suppression of DTMF and AGC, call progress, reproduction and recording of audio messages, detection of fax signals, conference, among other items, are performed in the module’s DSP, in addition to echo canceling, which is critical in IP telephony solutions. This robust architecture allows for the use of EBS for interconnecting up to 1000 TDM channels (34 E1/T1) with VoIP channels in a single server*.

Audible Response Unit (IVR), Telemarketing, Help Desk, Customer Service, Voice Mail, Call Center, Conference, IP PBX, among other features, are examples of applications in which the EBS-E1 VoIP can be used.
