Juniper makes $67.5m VoIP acquisition
Published: 30 Mar 2005 14:50 BST
Juniper Networks announced that it plans to buy start-up Kagoor Networks for $67.5m (£36m) in cash to expand its portfolio of carrier products.
Juniper, a rival of networking giant Cisco, will use technology from Kagoor to sell its communications equipment to telephone companies that are increasing their use of VoIP services.
Kagoor's VoiceFlow product falls into a new category of technology known as session border controllers. These devices are expected to become essential pieces of next-generation telecommunications networks as phone companies migrate their voice traffic from traditional systems to new networks that route calls over the Web. This migration to IP will allow carriers to consolidate their networks so that all traffic, whether it's email, Web surfing or voice calls, travel over a single network.
But moving voice traffic to an IP network isn't without problems. For example, firewalls used to protect corporate networks from viruses and worms do not recognise voice-signalling protocols. As a result, firewalls do not allow VoIP traffic to come into a corporate network from an outside network.
VoIP traffic is also problematic for companies that use network address translation, since computers attached to such systems generally can't figure out how to route VoIP calls using normal methods.
Session border control devices, built by Kagoor and other companies, including Acme Packet, Jasomi Networks, Netrake, NexTone Communications and Sonus Networks, eliminate these problems. These devices, which sit in a telephone operator's network, manage the handoff of IP traffic between corporate customers and the service provider so that firewalls and network address translation can be used. They can also be used to handle IP traffic between different service providers.
Kagoor's products have been installed in more than 100 carriers worldwide, most of whom also use Juniper IP routers, according to Juniper. The two companies also have several common strategic partnerships, including Lucent Technologies, Siemens and NEC. Last year, Lucent started reselling Kagoor's products, and Siemens has contributed to the start-up's $40m in venture capital funding.
Kagoor is based in San Mateo, California, not far from Juniper's Sunnyvale headquarters. It has a research and development facility in Israel, which Juniper plans to continue operating.
The acquisition is expected to close by the end of June. Juniper's last acquisition was announced in February 2004, when it acquired NetScreen Technologies for $4bn.
