 SIP trunking is efficient and more cost-effective than ISDN for connecting your

PBX to the public switched telephone network (PSTN)

 The SIP protocol is an internationally accepted standard – but it leaves room

for different implementations regarding protocol elements, message flow and features

 To ensure seamless interoperability and a full set of features beyond basic call, we are conducting

comprehensive tests with VoIP providers / ITSP in advance to avoid last minute surprises

 Our SIP implementation follows the SIPconnect Technical Recommendations

 industry-wide, standards-based approach to direct IP peering between SIP-enabled IP PBXs and

VoIP service provider networks

 Unify is in a leading position -

More than 55 VoIP Providers (ITSPs) for HiPath 3000 or OpenScape Office have been already
