2225 SIP Trunking & Carrier Connections

SIP Trunking & Carrier Connections is all about connecting to carriers to communicate VoIP phone calls, both carrier-to-carrier connections and business-to-carrier SIP trunking.

You'll learn how currently the only way for a competitive carrier to terminate a phone call on a Local Exchange Carrier to connect a VoIP call to someone with POTS is at the DS0 level using a gateway. We'll understand why this will be a native VoIP connection in the future, and the role of Session Border Controllers. Then we'll understand how a business can connect to the telephone system using a gateway and PBX trunks, and the advantages of the newer SIP Trunking services for business to PSTN connection.
