SIPMerge™ Server

SIPMerge Server is a SIP protocol converter designed for bridging SIP networks and allowing full SIP header manipulation.

SIP, as an evolving protocol, often causes interoperability issues between different vendors. Using SIPMerge, these differences are overcome by providing a stateful proxy that remains in the call path ensuring compatibility between servers, gateways and IP-PBXs

SIPMerge Server is ideally suited for Microsoft Exchange 2007 Unified Messaging (UM) Server integrations. SIP traffic from the UM Server is sent over TCP/IP unlike the majority of IP-PBXs and VoIP gateways which use UDP.

Key features
• Transport Layer Conversion (TCP/UDP)
• Payload Header Manipulation
• Security
• Load-Balancing
• Fault Tolerance
• Windows based remote configuration, reporting and debug
