SIP stands for session initiation protocol. SIP is an exceedingly simple protocol with many benefits. It also has plenty of powerful features to model the behavior of a very complex and very expensive traditional telephone PBX system. From an IT perspective, there is a lot to like about SIP. No matter the size of the business, SIP has the capacity to serve an entire organization.
SIP trunks are used for controlling multimedia communication sessions including voice and video calls over IP networks (VoIP). SIP is an extremely flexible telephony solution. It is especially helpful to companies with multiple offices and much more cost effective than analog lines, which do not have the capabilities of SIP trunks. In this post, we will focus on the capabilities of SIP trunks for VoIP and measure cost savings.
SIP trunking offers a huge savings reduction as compared to outdated analog voice network lines and packet switched data networks.
The average “in your pocket” savings is anywhere from 30%-80% on your monthly communications bill. What’s more, there is no expensive
investment for equipment. SIP trunks will work with much of the voice and data equipment you’ve already got in place.
With SIP trunking you can say goodbye to costly and inefficient BRIs, PRIs or PSTN gateways.
What are the benefits of SIP trunks? Why do I need them?\
- – Save money on long-distance service. Long distance service typically costs significantly less with a SIP trunk connection.
- – Eliminate IP-PSTN gateways (or even your entire PBX) Because SIP trunks connect directly to your ITSP without traversing the publicly switched telephone network, you can get rid of IP-PSTN gateways and their attendant cost and complexity. Some ITSPs will even host a PBX for you, taking over both the PBX hardware and user administration if you choose, with substantial cost savings from reduced complexity, maintenance, and administration.
- – Eliminate a redundant network. Deploying SIP trunking is a logical step towards the goal of having a single, IP-based network, rather than redundant telephone and data networks.
- – Eliminate BRI and PRI subscription fees with a SIP trunk connected directly to an Internet telephony service provider, you can dispense with costly BRIs and PRIs, replacing them with service that can cost significantly less. Furthermore, with SIP trunking you don’t need to buy lines in blocks of 24 or 32. Instead, you can buy the bandwidth you need, in smaller increments, and at better prices, as you require more. You only purchase what you need when you need it.
- – Extend the capabilities of Unified Communications applications with new services from ITSPs. With a SIP trunk in place, you can extend existing UC capabilities and add others. Look for ITSPs with pre-tested and certified interoperable SIP trunks with the industry’s leading UC providers such as Avaya, ShoreTel, and Microsoft. Also look for greater integration with mobile phones and presence information on multiple devices. SIP is not only limited to VoIP calls. SIP trunks can also carry instant messages, multimedia conferences and much much more.
