The biggest advantage of using SIP trunking is that it is cost-effective. With SIP trunking users can purchase exactly the number of channels needed, unlike with traditional PSTN-based telephony or PRI (Primary Rate Interface) implementations, that were connected with copper wires to expensive hardware-based PBX systems, where channels needed to be purchased in bundles and businesses often ended up paying for capacity they never used. A SIP trunk can have an unlimited number of channels, therefore a business needs only one, no matter the amount of calls the users expect at once. A SIP channel is analogous to a single incoming or outgoing call. SIP trunks use a packet switch network in which voice calls are broken down into digital packets and sent over the network to its final destination.Įach SIP trunk supports SIP channels. When using SIP trunks, a SIP provider connects one or multiple channels to a Private Branch Exchange ( PBX), giving users the ability to make local, long distance, and international calls over the Internet.
