What Exactly Is SIP Trunk?

SIP Trunk is an application layer protocol of the OSI layer that establishes a virtual connection between the traditional PSTN and cloud-based VoIP communications. SIP, or Session Initiation Protocol, is an application layer protocol that allows you to run your phone system over an internet connection rather than traditional phone lines. Trunking is the backbone of a telephone line used by multiple clients to connect to a telephone network.

The protocol is a set of rules and regulations to govern communication.

SIP trunking is what allows long-established, premise-based business phone systems to access the advanced features and benefits of VoIP.

What do mean by a SIP Trunk Provider?

The term “SIP provider” derives from the service “SIP trunking,” which allows businesses to connect their in-house IP PBX systems to the PSTN (Public Switched Telephone Network). When comparing SIP Trunk providers, you should consider the following:

  • Check for scalability and whether you can add and remove SIP Trunks as your needs change.
  • Understand what your failover system allows in the event of a power or network outage at your location.
  • Check to see if the provider provides number porting for any existing phone numbers you may have.

How SIP Trunking work

SIP is the most widely used format in IP telephony. It is a protocol that allows for the establishment of a VoIP session over the internet. You can have any of the following scenarios and more in this session:

  • Participate in a voice call with one other person.
  • Participate in a conference call with a large group of people.
  • Make video calls.

SIP trunks act as a bridge between your firm’s phone system and the Internet Telephony Service Provider (ITSP).

What is the difference between SIP & VOIP?

SIP is the protocol that is used to make those calls and connect multimedia sessions, with VoIP calls being just one type of session that they can handle.

The main distinction between them is that VoIP is limited to transferring voice data over the internet, whereas a SIP trunk can transfer packets of multimedia data. This could be done through voice, text, or video.

A VoIP call is carried out entirely over the internet or a private internal network. A SIP trunk, on the other hand, can be used to send data packets across any network, including ISDN (physical phone network), VPN, or the internet.

One of the most significant implications of this distinction is that a VoIP phone requires a computer to operate its software and connections, whereas SIP equipment can operate independently.

The protocol is stored in the phone exchange that you will have in your building as well as on the network provider’s equipment. If you handle sensitive data, you can even get a direct connection to your network provider for an extra layer of security.

on the other hand VoIP calls, are all controlled from a central location by a separate provider that controls the traffic. Not only this is less secure, but it also means that if their system fails, you will be unable to call.

What is the difference between SIP Trunking and SIP Channel?

“Trunks” are traditional groups of cables that connect local telephone exchanges to exchanges. This process became virtual with the advent of the internet. A trunk is now a collection of assigned “channels,” each of which can handle a certain number of concurrent calls. The number of channels you’ll need as a business is proportional to the number of calls you’ll be making and receiving at the same time. A good SIP provider will assist you in calculating this.

Channels are an important part of understanding how trunks are packaged and delivered. Every SIP Trunk includes several channels, which are essentially virtual versions of traditional phone lines. Each channel can handle two calls at the same time, one incoming and one outgoing. This is critical. If your company makes a lot of calls but rarely has more than two calls going at the same time, you won’t need more than one or two channels. If your company receives a large number of inbound calls at the same time, you’ll need to consider a large number of channels.

Advantages of SIP Trunking

SIP trunking provides greater purchasing flexibility to customers than TDM. TDM trunks typically support at least 23 voice channels, whereas SIP trunks can be purchased in any increment without the need for a dedicated wide area network (WAN) circuit. Customers can use existing WAN services, dedicated WAN connections, or even the public internet to implement SIP trunks.

An excellent SIP trunking service allows you to use your existing PBX equipment to migrate to an internet-powered telephone network.

You may be paying for extra lines that you aren’t using with a traditional phone line. Long-distance and international calls may also incur high charges. There’s also the cost of equipment upkeep.

SIP trunking offers simplified pricing, which is typically charged on a per-user basis. This has the added benefit of increasing predictability in your recurring expenses. SIP trunking with VoIP has a higher level of dependability. This means that you can continue to use your phones even if they fail. Calls can be forwarded to other lines, offices, or even your mobile device.

You can keep your business running smoothly and without interruptions no matter what happens in the background.
