Below are some fast facts about SIP Trunking.

SIP Trunking Defined

First off, SIP is basically the main technology you can utilize to establish voice communication sessions on data networks such as the Internet. A SIP session is either a multiparty conference voice call or typical VoIP call between two people. You get the same service from a conventional analog phone line with SIP trunk or trunk SIP, but instead of it acting as the physical wire, it serves as the virtual phone line provided by the SIP trunk provider. The provider would utilize your data circuit such as DSL, cable modem, or T1, etc. for connecting your telephone system back to their network.

Advantages of SIP Trunking

Primarily, SIP trunking is considerably more affordable than traditional analog phone lines and services, since you won’t have to maintain physical connections. Likewise, depending on the types and quantity of calls you make, SIP could save you at least 50% of your phone bill every month. The service also offers other features such as caller ID and DID.

The Cost of SIP Trunking

Because specific services vary from one provider to another, the cost would also vary. One factor that could determine its cost is the amount of SIP trunks you need. In general, organizations use one trunk for every two to three users, but you’d also have to consider your Internet connection since SIP trunks require sufficient bandwidth. Some SIP trunking providers charge customers a flat fee for every trunk and unlimited usage, while some charge a fee for each trunk for every minute.

SIP trunking offers organizations plenty of benefits to end users, such as lower costs, improved reliability, and scalable architecture. Speak to a SIP trunking provider to learn more about it and see how much you’ll need for your organization.
