SIP Trunking uses Session Initiation Protocol (SIP) to establish voice communication
between an Internet Telephony Service Provider (ITSP) like MAXXVOX and
a business IP PBX. ITSPs provide business VoIP communication over the
Internet. The connection of an ITSP is different from an Internet
Service Provider (ISP) connection because voice communication is enabled
with a SIP trunk, and an ISP can only provide an Internet connection. MAXXVOX is a business VoIP provider with expertly engineered IP
telephony products that offer 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 SIP PSTN gateway 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 makes a logical connection from one point to another through the Internet, making it possible to treat IP voice communication as just another application and deliver it as packets of data. The goal is to have the voice signal travel on the worldwide Public Switched Telephone Network (PSTN) as little time as possible because the cost of using those physical wires is much higher than the virtually free Internet. SIP Trunking price provides seamless access between the Internet and PSTN, resulting in immediate cost savings because calls travel the majority of the distance on the MAXXVOX network, avoiding the high cost of the PSTN.
