SIP Trunking

SIP Trunking

SIP trunking is the use of voice over IP (VoIP) and the internet to make phone calls instead of making calls through phone lines or PRIs. With SIP Trunking the Internet replaces the conventional telephone trunk, allowing an enterprise to communicate with fixed and mobile telephone subscribers worldwide. It also allows businesses to centralize and consolidate telephone services to save money and easily share capacity between multiple locations.

WebFones Business VoIP combines a centralized phone system, session boarder controller and SIP trunking to give business the ability to make calls over the internet, increasing flexibility and lowering cost. For instance, instead of having a phone line for every phone number like in a traditional phone setup, concurrent calls from any number can share all of the capacity without needing to worrying about hunt groups. It also provides increased mobility since there are no physical phone lines. All you need is some access to the internet or mobile phone in order to make or receive a call.
