Airtel Offers Advanced Voice Service Applications Powered by Kodiak Networks; India's Leading GSM Operator Offers Innovative, SIM-Based Voice Applications Targeted at Groups.

NEW DELHI, India & SAN RAMON, Calif. -- Airtel, the leading GSM operator in India and Kodiak Networks, the global provider of advanced wireless voice systems, today announced that Airtel has deployed the Kodiak Networks Real-Time Exchange(TM) (RTX) System to offer a suite of advanced voice services called Airtel Group Call (AGC) to their customers. AGC applications are being offered via Kodiak SIMpower(TM), an innovative thin client which enables premium voice service functionality on existing GSM handsets.

Airtel is the first operator in the world to commercially offer the following suite of AGC voice applications to their nationwide base of GSM customers on a SIM card:

--Voice Bridge - Provides fast and easy set-up of full-duplex, mobile-originated conference calls with up to a total of 10 wireless and landline participants. With Airtel, business colleagues, social groups and families can instantly initiate an instant conference call. Within seconds, conference calls can be made to any combination of dialable telephone numbers.

--Instant Availability - Similar to popular Instant Messaging applications, this feature displays the current availability of friends, family, coworkers, customers and suppliers to receive a wireless call. Availability states includes "available", "do not disturb", and "offline".

--Group SMS - Compliments existing voice services by enabling discreet text communications when recipients are not available. Group SMS simplifies message addressing, group selection, and delivery, while minimizing key strokes and menu navigation.

--Quick Groups - Offers users the ability to form groups within the application by simply selecting people from Contacts to create a quick group and initiate a call. Users can instantly reach their associates or friends to share news and updates.

--Contact and Group Management - Enables Airtel subscribers to instantly create, modify and delete individuals, groups, and group members, directly in their SIM and also over the Internet. Contacts are then automatically backed up on the Airtel network and can be easily restored in the event of a new, lost or stolen phone.

"We selected Kodiak Networks based on their overall system performance and ability to deliver innovative voice applications to our customers via Kodiak SIMpower," said Deepak Mehrotra, CEO, Airtel Karnataka. "We believe that offering AGC voice-based services that simplify group communications is critical to our nationwide GSM customer base."

"Airtel is the first operator within India to commercially launch this suite of advanced voice services to their customers," said Kris Patel, EVP products and customer support and CTO, Kodiak Networks. "We believe that using the SIM card as the delivery mechanism for these voice applications will help rapidly expand service adoption, as subscribers can use their existing handsets."
