SIP Trunking

 

SIP Trunking uses Session Initiation Protocol (SIP) to establish voice communication between an Internet Telephony Service Provider (ITSP) such as Lightyear, and a company’s IP-PBX. ITSPs provide VoIP communication over the Internet. They are different from ISPs (Internet Service Providers) in that voice communication is enabled with SIP, however, with ISPs, only the Internet connection is provided. Lightyear Network Solutions is a business VoIP provider with an expertly engineered IP network that offers greater reliability, features and functionality than the public Internet. Businesses are able to migrate to IP Communications from traditional TDM gradually, using their legacy CPE with a gateway IAD device ( Dynamic T1)  or all at once with an IP PBX. This flexibility allows communication between any device that is IP enabled, including SIP phones, smart phones, PDAs and computers.

SIP Trunking

 

As shown in the diagram, it is possible to avoid PSTN charges altogether if both the originating and receiving parties use VoIP (Voice over Internet Protocol) for voice communication. If both parties use SIP to establish voice communication, their calls can travel on the Internet for virtually no charge. The only charge would be a reduced rate charged by their ITSP provider.
