Ingate and Dialogic Team Up on Enterprise SIP Trunking Solution

    Interoperable Solution Enables Secure SIP Trunking for Legacy PBX and
Contact Center Environments

    STOCKHOLM and PARSIPPANY, N.J., May 26 /PRNewswire/ -- Ingate(R) Systems,
which develops firewall technology and products that enable trusted Unified
Communications, and Dialogic Corporation ("Dialogic"), a global provider of
world-class products and technologies for multimedia and signal processing,
today announced that they have completed the necessary testing to validate the
Dialogic(R) 2000 Media Gateway Series (DMG2000) as interoperable with Ingate
SIParator(R) and Ingate Firewall(R) products. The combination of a DMG2000
gateway and an Ingate SIParator or Ingate Firewall will allow enterprises
utilizing legacy PBX and Contact Center systems to easily and securely adopt
SIP trunks as a replacement for traditional PSTN voice services.

    SIP trunking has emerged as one of the hottest voice service solutions in
the business communications market since the divestiture of AT&T in the
1980's, and the ensuing long distance service competition. Both enterprise
class and small to mid-sized business (SMB) customers are eager to adopt VoIP
service as a means to reduce voice service costs, particularly in the current
economic environment. Adopting SIP trunking service puts business customers in
a position to benefit from both lower costs and the multimedia capabilities of
the SIP protocol to extend their communications between business partners
beyond basic voice in the future.

    "To date, most SIP trunking providers and resellers have focused on the
opportunity to migrate SMB class customers from PSTN service in concert with
an upgrade to a SIP-ready IP-PBX system. While this opportunity focus remains
logical and compelling, there is also a significant opportunity to migrate
Enterprise class customers who maintain legacy (non-SIP) PBX and contact
center systems" stated Steve Johnson, President of Ingate Systems. "The
combined security features of the Ingate SIParator with the SIP to PBX trunk
conversion capability of a DMG2000 gateway enable a cost effective, secure and
reliable SIP trunk interface for these customers."

    SIP trunks are delivered to business customers over broadband IP data
networks. With this interoperability solution, both Ingate and Dialogic
products are deployed on the customer premises to support the SIP trunking
service.  The Ingate products are deployed at the network edge between a wide
area IP network and the corporate LAN, securely passing SIP signaling and VoIP
media streams to and from the corporate LAN. The Dialogic gateway resides on
the corporate LAN and is connected to the legacy PBX or contact center via
traditional T1/E1 trunk ports. The DMG2000 gateway passes the SIP Trunk
signaling and media from the Ingate SIParator to the PBX by emulating
traditional PSTN trunk services.

    "We are very pleased to announce this interoperability with Ingate
today," states Franz-Josef Eberle, General Manager, Dialogic Enterprise
Gateway Product Group. "Ingate is a recognized leader in securing SIP trunking
for business customers, which comprise a critical piece that can be overlooked
by some device vendors. We believe this solution set truly opens up a whole
new Enterprise market opportunity for SIP Trunking providers and their
