BERN, Switzerland, July 21 --

- Field-proven interoperability between IntraSwitch(c) VoIP application
software and SmartNode(TM) VoIP gateways delivers convenient, cost-saving
unified communications with rapid, trouble-free deployment for large businesses.

- SmartNode(TM) VoIP... more than just talk.

Patton-Inalp Networks AG -- creator of SmartNode(TM) industry-leading VoIP
gateways-- together with Centile -- creator of IntraSwitch(c) VoIP application
software -- announced today they are working together to provide integrated
unified communications (UC) solutions for large enterprises.

The field-proven interoperability between Centile’s IntraSwitch(c) VoIP
application software and Patton’s SmartNode(TM) VoIP gateways ensures
rapid deployment and, trouble-free operation for large companies transitioning
to next-generation unified communications networks.

Managing Director of Centile, Bertrand Pourcelot said, Extensive SIP
interoperability--proven in the field--enables Centile and Patton-Inalp to
deliver enhanced integrated solutions to enterprises.

Centile and Patton have recently deployed converged-IP solutions for French
firewall provider Arkoon’s newly commissioned offices in Paris and Lyon
and AttijariWafa Bank with sites locations in Casablanca and throughout France.

The troubleshooting has all been done, said Ramon Felder, president of
Patton-Inalp, so it works right out of the box. Our seamless solutions are
up-and-running today in real-world business networks. Companies can choose
Patton and Centile with confidence.

A high-precision clock, unique to SmartNode(TM), eliminates common
interoperability failures with DECT, PBX and FAX communications when VoIP is
deployed in the context of ISDN systems.

Mr. Pourcelot continues, When deployed with Centile IP Telephony solutions, the
powerful call-routing and first-rate ISDN capabilities of Patton-Inalp products
deliver best of breed enterprises communications.

IntraSwitch(c) provides such IP-PBX and UC functionality as conferencing, hunt
groups, presence, and find-me-follow-me.

SmartNode(TM) gateway-routers complement IntraSwitch(c) functions with
SIP-based call routing and a Unified Communications Agent (UCA) that provides
any-to-any multi-path switching for seamless integration with existing Telco
networks and ISDN PBX systems.

Mr. Pourcelot concludes, Centile appreciates such responsive partners as
Patton-Inalp who provides excellent support, consistent distribution channels
and very aggressive product line pricing. This is the combination Centile
customers are looking for.

Besides first-line stability and reliability, SmartNode(TM) delivers voice
quality comparable to ISDN, while rich ISDN features allow users to use legacy
handsets and PBX functions exactly as they are accustomed.

Patton is also stimulating analog VoIP markets with recent price cuts on
SmartNode(TM) FXS gateways.

On 1 January 2009 Patton marked their 25th anniversary and named Robert R.
Patton as CEO.
