CLEC Adds to Portfolio of IP Telephony Solutions that Work Seamlessly with
its SIP Trunking Service

TORONTO – January XX, 2011 – Iristel Inc., a Voice over Internet Protocol (VoIP) operator licensed by the Canadian Radio Television and Telecommunications Commission (CRTC), today announced that its Session Initiation Protocol (SIP) Trunking service is fully compatible with software-based IP (Internet Protocol) PBX (Private Branch Exchange) phone systems for Windows™ from 3CX, an international developer of telecommunications software.

Iristel’s SIP Trunking service enables customers – including small to midsize businesses (SMBs) – to converge local, long distance and private voice traffic on a single IP backbone and reduce network costs. Rigorous interoperability tests were completed by Iristel to ensure compatibility between its SIP Trunking service and 3CX’s software-based PBX, thereby adding to the list of IP telephony solutions that work seamlessly with Iristel’s SIP Trunking service.

“As a CRTC-licensed CLEC, Iristel is not only committed to providing customers with high quality coverage in Canada and around the world, we also want to help customers maximize their IP investments,” says Samer Bishay, President and CEO, Iristel Inc. “To get the most out of your PBX, you need to start with a quality system; but you also need great SIP trunks that will enable you to innovate and add new technologies as business needs dictate. This interop broadens our portfolio to bring the best of both worlds to customers.”

By ensuring its network is compatible with key IP telephony solutions, Iristel offers a standards-based platform that enables customers – especially SMBs – to economically and efficiently migrate to new technologies without immediately abandoning investments made in their existing IP infrastructure.
