The IP04 is a high quality, stable PBX without any moving parts and a very small footprint. The power consumption (<5W) as well as the heat dissipation is kept at an absolute minimum.

An Open Source Line Echo Canceller (OSLEC) ensures high quality conversations without the need for additional expensive hardware.

Replaceable FXO / FXS modules make it easy to adapt the IP04 to the requirements of most companies (for example 1 FXO for an analogue backup line, 3 FXS for analogue telephones).

Very efficient versions of GSM, Speex and G729 codecs have been ported to the IP04 platform.

The IP04 has successfully passed the following SIP tests:

500 000 VoIP calls with 10-20 concurrent calls during a 12 hour period
40 000 calls distributed over the 4 analogue ports, performed over a period of several days
