subscriber interface board


The KFXO-IP (KFXO-80IP, KFXO-40IP) was developed with a powerful set of DSP-based resources making it very attractive for the CTI, Soft PBX, and TDM/IP gateway market. The KFXO-IP is an excellent choice for applications using analog lines requiring advanced voice resources and IP channels with excellent echo cancellation.

The available voice resources allow using the board in various applications, such as: IVR, voice mail, recorder, dialer, among others. IP channels with the SIP protocol enable using the board in IP Gateway applications for analog lines, Soft PBX VoIP, and many other applications needing VoIP resources.

For Soft PBX applications, Khomp has prepared and distributes a channel driver for Asterisk or end_point for FreeSWITCH along with the board.
