4 ports FXO VoIP Gateway – SP5250+ Series

The SP5250+ Series analog VoIP gateways are feature-rich and cost-effective products designated for telecom operators to provide telephony services with security-enhanced capabilities in the modern complex networks.
The SP5250+ Series VoIP Gateway empowers service providers delivering carrier- class IP Centrex service over a Total-IP NGN / 3GPP IMS infrastructure in a more secured way.
The SP5250+ gateway provides a connection platform between traditional POTS lines and the Internet. Over various broadband technologies including xDSL, HFC, wireless and fiber, the SP5250+ Series carries toll quality voice, fax and data traffic simultaneously in a cost effective way. In addition, the SP5250 Series supports intelligent features like long loop, line testing, polarity reversal, caller ID, call transfer, call waiting and 3- way calling. The ideal applications include MTU/MDU, virtual PBX, IP Centrex, PBX extension and hosted telephony services.
