Overview:

GSM VoIP gateway ETS32x8G is newly designed IP to GSM gateway supporting maximum 32 ports 256 SIMs of GSM Voice interface, it can effectively realize the smooth transition between PLMN(GSM) and VoIP network. Compact cost effective design and system architecture of GSM Gateway ETS-32x8G provides customer satisfaction in high quality,good performance and system reliance.

Mostly important,GSM Gateway ETS-32x8 features with new functions such as multi- SIM rotation, Human behaviour,BTS rotation,proxy server encryption for anti IP block, ETS bandwidth optimization (SBO), Auto IMEI change and generation,auto activation SIM card etc.

This product uses the state-of-art technology voice compression and Smart QoS of ETS to maintain the maximum voice quality under fast internet line and slow internet line as well, thus It is an ideal gateway for heavy duty VoIP call termination (VoIP to GSM) and Origination (GSM to VoIP), it is fully compatible with leading soft switch and SIP server.
