SIPconnect Interface Specification Launched by Cbeyond and Others

February 8, 2005


SIPconnectRelease of a new draft “SIPconnect Interface Specification” provides standards-based direct IP peering between IP PBXs and VoIP service provider networks.

Cbeyond Communications and five other IP telephony vendors, Avaya, BroadSoft, Centrepoint Technologies, Cisco Systems, and Mitel, have developed a draft best practices specification to guide interoperability between IP PBXs and VoIP service provider networks.

The rapid deployment of IP PBXs in businesses and the transition to VoIP by service providers has created an opportunity for direct IP peering between IP PBXs and VoIP-enabled service providers which would lower costs, reduce voice latency, and provide for end-to-end SIP signaling for PSTN termination.

The newly released, publicly available SIPconnect Interface Specification leverages the SIP and other IETF VoIP protocols to provide the consistent, industry standards-based approach to interconnection essential to the future of packet-based communications.

Cbeyond Communications, Avaya, BroadSoft, Centrepoint Technologies, Cisco Systems, and Mitel have all indicated their intention to develop products and services that comply with the new draft specification, to the extent that any of their current product lines do not already do so.

They state that SIPconnect specifies a reference architecture, required protocols and features, and implementation rules necessary for seamless peering. It defines a clear and consistent architecture that enables IP PBX vendors and service providers to rapidly and cost effectively deploy VoIP services. They invite the rest of the industry to join and follow them.

Ingate Releases New Tools for SIP Real Time Communications Through Firewalls

December 17,2004


Ingate’s new Firewall 1600 and SIParator 60 high-capacity products enable SIP-based VoIP, IM, presence, and other realtime person-to-person IP communications in large enterprises.

Ingate Systems AB announced two new products for organizations with high demands for capacity, throughput and reliability of SIP-based IP communications: the Firewall 1600 and SIParator 60.

SIP (Session Initiation Protocol) traversal of firewalls is an ongoing hurdle for the rapid adoption of this protocol for realtime communications in enterprises, and one which all of Ingate’s security products address.

Both of these products deliver IP-PBX functionality, SIP-enabling technology, and support for Microsoft Office LCS (Live Communications Server) 2005, combined with network security. Both are 1 U high and feature six interfaces, two of which can be used at Gigabit speed, and each supports up to 360 simultaneous RTP sessions (e.g. VoIP calls). Both are managed via an HTML-based graphical user interface.

The Firewall 1600 includes 10 SIP user licenses and five SIP traversal licenses, while the SIParator 60 has 50 SIP user licenses and 25 SIP traversal licenses. The SIP user licenses can be used for the registration of SIP user agents such as phones and soft clients, while the SIP traversal licenses allow one call per license to traverse related firewalls at the same time. Additional licenses are available optionally.

The 1600 and 60 are designed complement an IP-PBX, and support functions such as call transfer, call hold and voicemail. Their compatibility with Office LCS 2005 allow voice, video, IM and presence applications to work outside the LAN.

Ingate Systems is based in Stockholm and Linköping, Sweden, with a wholly-owned subsidiary, Ingate Systems Inc, in Hollis, New Hampshire. Ingate Firewalls solve the NAT traversal issues inherent in using SIP.
