If your phone system operates poorly or inconsistently, you may want to learn about SIP Trunking and how it can help your organization improve its call quality.

Coeo has delivered hundreds of SIP Trunking services and knows how important a high-quality good calling service is to an organization.

We want to provide you with all of the information you need so you can invest in the best calling service for your organization.

By the end of this article, you will know what SIP Trunking is, how it works, and what it is used for.

What is SIP Trunking?

Session Initiation Protocol (SIP) is an application layer protocol that allows you to run your phone system over the internet rather than a traditional phone line.

Trunking serves as the backbone of phone lines used by many users which connect to a telephone network.

The main objective of SIP Trunking is to bring a standard PBX phone system to the cloud. This allows you to achieve lower costs and scalability of the cloud-based phone system while utilizing your existing PBX phone system.

A Private Branch Exchange (PBX) phone system is a private phone system that enables internal and external communication. This phone system is made up of hardware and software that connects to hubs, switches, and routers.

SIP Trunking is provided to you by a SIP provider just like any other phone service provider. SIP may also be used as part of your unified communications allowing you to synchronize your communication channels improving productivity and efficiency.

How does SIP Trunking work?

SIP Trunking turns your PBX phone system into a cloud-based phone system without making any major changes to your infrastructure.

To do this, SIP trunks act as the middle ground between your phone system and the Internet Telephony Service Provider.

SIP Trunking uses VoIP technology which converts voice calls to digital signals and sends them through a network connection to their intended location.

SIP Trunking sends calls over data networks rather than over copper wires that traditional calling services use.

Because SIP Trunking operates completely online, this eliminates the need for physical phone lines. This allows you to host conference calls and run video calls in addition to regular one-on-one voice calls.

Additionally, Direct Inward Dialing (DID) is a service that lets any phone number directly call a particular SIP phone assigned to your business. This allows you to have multiple telephone numbers attached to a single phone.

A DID number can be purchased alongside a SIP Trunk. However, before purchasing a SIP Trunk, there are a few things you need to make sure your company has in order for SIP Trunking to work properly.

●      Strong internet connection

Since your phone system will now operate over the internet, your organization must have a strong and secure internet connection that allows your calling service to operate as efficiently as possible.

●      SIP-compatible PBX

Most PBX phone services can easily be transitioned into a SIP phone service however, if your PBX line is outdated, it may not be compatible with a SIP phone service. Making sure you can use your existing phone service is important.

The easiest way to determine this is by simply contacting your future SIP provider and asking them if your current phone service is compatible with their trunks.

●      VoIP phones or VoIP adaptors

SIP Trunking requires VoIP phones for it to work properly. A VoIP phone is simply a phone that uses the internet rather than copper wire to make calls.

You can use your old phones for SIP Trunking if they are compatible. You would just need a VoIP adaptor to turn them into VoIP phones.

●      Strong network connection to your phones

In addition to having a strong and secure internet connection, the same is true with a network connection to your phones. Your phones must be connected properly to your network in order for them to operate efficiently.

What is SIP Trunking used for?

SIP Trunking is used to replace Primary Rate Interface (PRI) technology. PRI is the traditional phone system that delivers lines of voice over copper lines.

Since PRI hardware has become outdated, it can be costly to maintain. With SIP Trunking, there is minimal hardware involved making it much cheaper, and it is delivered over the internet making it faster and more reliable.

SIP Trunking can also be used for growth and scalability. With no copper wires, it is much easier to add phone lines than it would be in a traditional PRI system.

If your business is rapidly growing, you can add new phones quickly and easily. On the other hand, if your organization needs to get rid of lines and take phones away, this can be done just as easily as adding them.
