MIAMI, FL - February 8, 2001 - Leading SIP communications software developer, Indigo Software today announced at Internet Telephony Expo its continued commitment to Level 3 Communications (NASDAQ: LVLT) (3)Works^SM Voice Certification Program, having designed and put in place the two most advanced tests in the program. Conceived to enable software developers and equipment vendors to test against Level 3's Session Initiation Protocol (SIP) interface, the initiative gives the world's leading communications technology providers the opportunity to ensure interoperability between IP carrier and SIP solutions designers.

SIP is an open, Internet-genuine protocol for establishing and managing multi-party, mixed-media sessions over converged networks and allows the immediate commercial deployment of feature-rich services that go far beyond simple VoIP calls. Regarded within the industry as a service-enabling technology, SIP has gained concrete support from IP backbone architects and converged communications service providers.

"We're dedicated to Level 3's (3)Works program, as it illustrates the viability of emerging SIP infrastructures," said Emmanuel Bertrand, CEO and CTO of Indigo Software. "In addition to the high levels of interoperability that we can demonstrate with other leading vendors, the Level 3 initiative provides us with a challenging SIP ecosystem to test against an IP carrier interface with a global infrastructure, and to drive the development of next-generation communications services."

"It is imperative to have the support and commitment of leading software solutions providers for such advanced testing," said Ike Elliott, Senior Vice President of Global Softswitch Services for Level 3. " We're especially pleased to have Indigo Software design and conduct two difficult tests in the (3)Works program," added Jason Bach, Technology Development, Global Softswitch Services at Level 3.

"The success of these tests will confirm what we've believed from the outset - the commercial good sense of widespread deployment of SIP-based, IP solutions which offer a feature-rich alternative to legacy telephony," added Edward Keegan, Head of Business Development, Indigo Software.
