A SIP trunk is a direct connection between your company and an Internet Telephony Service Provider (ITSP). Normally you need special hardware to extend your VoIP telephony beyond your company’s firewall. SIP trunking eliminates the need for that hardware.
SIP trunks can also provide you with advanced features such as instant messaging, user presence information such as “busy” or “away” status, multimedia conference sessions, and Enhanced 911 (E911) emergency calls. Your investment in SIP trunking can provide a substantial return on your capital investment. They are less expensive to operate, maintain and upgrade. Additionally, ITSPs deliver services at substantial savings.
Because it is easier to configure and less expensive to design, operate, maintain, and upgrade, and because Internet Telephony Service Providers (ITSPs) deliver services at substantial savings, your investment in SIP trunking can give a quick and substantial return on investment. Simplify your company’s telecommunications infrastructure and prepare for the latest real-time communications technology.
SIP trunking offers the following cost savings:
- Long distance calls in the U.S. are included at no additional cost.
- You can cut manageability costs and reduce the complexity of deployment
- Eliminate special hardware such as PSTN gateways
- Eliminate T1/PRI costs
