Certification and Vendor Qualification
Service provider certification is extremely important and assures users that any interoperability issues have already been resolved by vendors before the equipment is installed. However, SIP Trunking service provider certification alone is not sufficient. A demarcation device that is qualified for Microsoft Lync 2010 as well as certified by the service provider is the only proven method for guaranteed interoperability.
