SIP Trunk technology is not very widespread in the knowledge of most companies, it is the telecommunications manager of a business who knows how it works and what are the best options to configure it according to the communication needs of each company. Discover how does a SIP Trunk work.
That is why in this post we want to explain in a simple way how a SIP Trunk works and what are the advantages of using this channel to send and receive calls.
Are you wondering what a SIP Trunk is?
A SIP Trunking is an internet connection channel that connects your virtual switchboard (PBX) with the public telephone network.
We tell you how a SIP Trunk works, the best telephony solution for your business.
How a SIP Trunk works
SIP Trunk technology works through the internet network. It transforms the voice into data packets so it can be transmitted over the internet. Just with an internet connection you can send and receive calls through a SIP channel.
The calls leave the virtual switchboard of the company and travel through the Internet thanks to the SIP Trunking channel, which sends it to a mobile or landline phone. SIP trunks establish a connection channel for small switchboards or countless connections for large companies and call centers.
The SIP Trunk replaces traditional analogue connections with a public or private internet connection of a company through a SIP provider.
The rates offered in the market are usually two. On the one hand, you can pay for the minutes of calls made or use plans with unlimited minutes, but we must take into account the number of channels contracted since that will limit the simultaneous calls. For example, if a company has 10 SIP Trunk channels, it can make only 10 simultaneous calls.
What do you need for a SIP Trunk to work?
For a company to use this online service, it needs to have the following features:
- High-quality internet connection
- A VoIP telephone provider
- IP phone or softphone
- Fixed IP address
Advantages of using a SIP Trunk
With the SIP Trunk service, you can get the following benefits:
- Savings: the costs of the minutes of SIP calls are much lower than traditional telephony. Also, monthly fixed fees decrease or disappear, you only pay for the minutes used. On the other hand, charges for incoming calls, long-distance calls and IT and maintenance costs are drastically reduced or eliminated.
- Flexibility: with SIP calls you can connect one or several telephone numbers with many telephone lines, which offers the possibility of hiring lines or channels depending on the volume of calls the company has. Something that is a benefit compared to traditional telephony, which is more rigid and expensive, since they force you to hire a certain number of lines as a package.
- Telecommuting: the SIP Trunk and the virtual switchboard are connected through the internet, so an employee can work remotely and make calls from anywhere in the world. The distances do not matter and still maintain the same cost of calls.
- Integration: allows integration with a PBX or virtual switchboard. This integration also offers us the possibility of including a CRM, ERP or the company’s applications, as well as software for call centres.
- Security and stability: it is a very reliable technology since having no cables prevents electrical failures or circuit breakages. Furthermore, IP phones can be diverted to other data lines to ensure that calls continue to come in case there is a problem with the provider being used.
