charges. Voice quality for conversations using VoIP technologies can greatly exceed traditional
telephone services. Note that CounterPath Solutions, Inc. does not provide a telephone service,
but instead offers software to use such services. Please refer to Section 2.1.1 of this guide for

eyeBeam uses open standards, which permit inter-operability between products from all vendors
in a given industry. Open standards give consumers a choice, rather than being locked-in to the
proprietary solutions of one vendor. CounterPath Solutions plans to use open standards for future
VoIP products as well, with hopes that customers will recognize CounterPath’s commitment to
open standards and excellence in high-quality VoIP softphones.
eyeBeam uses the Session Initiation Protocol (SIP) for session signaling, ITU codec standards for
voice and video (G.711, G.723, G.729, H.263, H.264), and the SIMPLE standard for instant
messaging (IM) and presence.
