What is a SIP trunk?

A SIP trunk or SIP line is a telephone line that operates over IP using the SIP protocol. These telephone lines connect voice traffic from the VoIP telecommunications provider to the customer’s PBX. In most cases, the phone number can be ported to a SIP trunk or you can choose to use new numbers. Using SIP trunks will bring many benefits to any company that needs to make a high volume of national and/or international calls. Costs will be lower as VoIP line rates and calls made over the internet have lower prices than traditional telephone networks. In addition, you will be able to provide better customer service by offering them different geographic and international numbers that will make calling them more secure. Moreover, you can move your locations anywhere and keep the same phone numbers. With a SIP trunking provider, your business will get great flexibility as it is very easy to add channels to your SIP trunk and do it immediately. On the other hand, the VoIP system allows you to take advantage of all the benefits of a virtual switchboard to improve productivity, mobility and customer service.

SIP trunk provider for virtual PBXs

A SIP trunk provider will allow you to make the transition from a conventional PBX to a virtual PBX. With a SIP trunk system, you will have the link that connects the PBX between the company and its premises with the entity in charge of providing IP telephony. What the SIP trunk does is connect the IP network to the conventional telephony network via the Internet, which will allow you to enable the use of a virtual switchboard in your company. As we have already mentioned, this system has many advantages, including cost savings due to the fact that the connection of the calls is made over the internet and not by wiring. To all this, we must add the benefits of the virtual switchboard.

Bandwidth requirements for using a SIP trunk

The bandwidth you will need to use a SIP trunk to make VoIP calls will depend on the number of simultaneous calls. The minimum recommended bandwidth for internet calls is 100kbps to ensure that you always have the highest quality VoIP calls. In the case of freelancers or small companies that have a telephone number and an extension with 1 or 2 channels, 100kbps will be enough, although it is advisable to have more to be able to carry out other activities on the internet simultaneously in a fast and comfortable way. In the case of larger companies with a higher number of extensions and channels to be able to make simultaneous calls, higher bandwidth will be necessary. For 5 or more simultaneous calls, 150kbps is required and 500kbps is recommended. For 10 simultaneous calls, you will need 300kbps, but 1mbps is recommended.  

SIP trunk bandwidth calculator

There are bandwidth calculators such as SIP Bandwidth Calculator where you can get the bandwidth you need to use a SIP trunk depending on the number of simultaneous calls you expect to have. For example, if you have 50 employees and you expect 10 of them to be on the phone at the same time you would choose 10 simultaneous calls.
