Global SIP trunks can give your office phone system a boost by connecting different extensions through the internet. Let’s have a look at what global SIP trunking is and if your company needs a new phone system.

What is SIP Trunking?

Session Initiation Protocol (SIP) is a means of initiating and sending voice and other unified communications services through the internet. And global SIP works with IP-enabled private branch exchange systems (PBX). A PBX system connects incoming calls with any extension within your company. Before SIP options were available, calls were made through public switched telephone network (PSTN) lines. But now, SIP trunking takes this a step further by enabling the PBX to send and receive calls via the internet eliminating the need for standard PTSN. And so, SIP gives voice over internet protocol (VoIP) capabilities to your regular PBX. It works with virtual phone lines that run through bandwidth data.

VoIP capabilities enable the ability to transmit voice, text, video, image, and other files from one system to another. And companies are increasingly switching to VoIP office systems to streamline and organize their internal and external communications. With global SIP trunks, you can stay connected with your team as well as your customers through different mediums.

How Does SIP Trunking Work?

Global SIP trunks transmit voice, video, text, and other unified communication from one user to the next via the internet. SIP trunks work with VoIP to convert voice signals to digital packets in order to transmit them effectively and accurately. Originally, PSTN cables were used to transmit calls between two to more users. With SIP trunking, users can now deliver calls over an internet protocol instead.

Global SIP trunks can easily integrate within a PBX system, so no additional equipment is needed. This allows them to communicate across geographical boundaries and virtually without worrying about high long-distance calling fees or logistics. This adds more flexibility, mobility, and scalability to a business phone system.

SIP Trunks and SIP Lines

SIP trunks hold multiple SIP channels or SIP lines. Each SIP channel is one inbound or outbound call. Therefore, being able to have multiple channels in one global SIP trunk means that users can place multiple calls simultaneously.

For example, if your provider offers you a SIP trunking service with 30 SIP channels, this means that your business can make and answer 30 calls concurrently. Therefore, your business does not need to invest in purchase phone lines.

Small- to medium-sized businesses are often able to conduct operations effectively with just one trunk. However, how many SIP lines does your business need? This depends on the average number of calls occurring simultaneously. In other words, how often do your teams communicate with customers or business contacts at the same time? Do you have periods of high call traffic often? and so on. Global SIP trunk providers offer a variety of plans to meet varying business needs; these include but are not limited to:

  • Multiple or unlimited channels
  • Unlimited channels with a set number of minutes
  • Limited channels with unlimited minutes
  • Multiple trunks for various offices (or office locations) within the same network.

Speak with your SIP provider to find the right plan for your business.

Additionally, you can get virtual phone numbers from a SIP trunk provider like Global Call Forwarding that works alongside your virtual office system.

1. Easier on the Pocket

VoIP is known for providing high-quality service at cheaper and more reasonable rates. And it becomes even more worth it when you consider that it is transmitting multimedia files at those rates, something traditional lines cannot do.

2. Supports and Encourages International Calling

For businesses with an international clientele, this service can help reduce your long-distance calling charges. And this is simply because the call is routed over an international call forwarding service through the internet. You can get virtual numbers such as toll free numbers or local numbers.

3. Offers Unlimited Number of Channels

SIP trunks host an unlimited number of channels so you can use it no matter what your bandwidth is. Sold in smaller quantities, these lines are easy to set up and more cost-effective than traditional lines which sell in bundles of 23. And you can have multiple virtual lines running through the system.

4. Improves Scalability

SIP trunking also allows you to scale up or down easily as lines can be added in gradually based on your need and convenience. And, you can increase capacity at any time.

5. Reliability

Since SIP services work on broadband internet connections, they can enter and cover different geographic areas. And so, with SIP, you can set up and manage unlimited geographic and non-geographic numbers. This is perfect for companies with remote offices and employees.

6. Helps Adopt the Follow the Sun Model

Use global SIP trunking to smoothly switch to the Follow the Sun model, a customer service approach aimed at offering 24/7 global customer support.
