Voip Gatway
Untitled Document Introduction

WellGate 5250 is not only a VOIP trunk gateway but also a UNIVERSAL VOIP GATEWAY. It navigates the calls in between H.323, SIP and PSTN freely, not simple PSTN to VOIP calls or vice verse. By providing both route and unroute VOIP to VOIP calls, Wellgate 5250 can be used to implement SIP and H.323, SIP and SIP, H.323 and H.323 calls easily. It increases more revenues and protects your investment.

Wellgate 5250 supports PSTN and VoIP (H.323/SIP) side prepaid and postpaid service. It provides a built-in practical internal AAA service for small deployment and also an external RADIUS interface for large deployment. By integrated with built-in PSTN and VOIP IVR (Interactive Voice Response), service provider can implement their service easily without limitation. A web-based voice prompt management GUI is also provides to simplify the deployment of IVR related service.
