Connection describes something that can be dialled 🔔 and make calls ☎️ 📞

In the world of VoIP (SIP), a Connection is a SIP endpoint (SIP device)

VoIP and SIP

VoIP (Voice over Internet Protocol) and IMS (IP Multimedia Subsystem) are sending voice calls in digital packets over the Internet as opposed to sending them as analog voltage signals, as was the case with the old telephony lines. VoIP is based on the SIP protocol, and whenever someone says VoIP you can think of it as SIP. We will name all devices that you can connect to VoIP networks a SIP endpoints, SIP phones, or SIP devices

SIP devices can be divided into 3 categories:

  • IP phones

  • Softphones

  • and others, like: intercoms, alarms, doorbells, etc.

IP phones are hardware that you can put on your desk, and so they are frequently referred to as desk phones. The most popular desk phones are produced by Yealink, Cisco, and Polycom

Softphones are similar, but they do not have a handset or headset, they are just programs, a software that uses your computer's or your mobile phone's microphone and speaker as audio interfaces

In any case, SIP device must be registered with VoIP provider to receive calls

Creating a Connection

When you create a Connection, you define 3 parameters:

  • Name

  • SIP user

  • SIP password

Registering to Connection

Only Name and SIP user are mandatory when you are creating a new Connection but if you want to register to a Connection you should set a SIP password as well (not always you need to register to a Connection, see Virtual Connection below)

Connection's SIP user and SIP password are SIP credentials which let you register from a SIP device ☎️ of your choice as a Connection for making and answering calls

Once Connection is added, you need to open configuration settings on your SIP device and use the parameters you set up for the Connection (Name, SIP user, SIP password). If it is asking you about a SIP domain (SIP provider, VoIP provider, SIP server, or similar type of thing) type

sip.voipnumber.net

Once it's done, click REGISTER on your SIP device and you will get online immediately ✅

SIP devices differ in how they present these settings to the user on their UI. Check out these quick guides for more details and a handful of examples for setting up Zoiper, Bria, and Yealink IP desk phones:

  • Register a Softphone (SIP phone)

  • Register IP desk phone

Virtual Connection

Dialing a Connection

Inbound Action (Connection's inbound action)

When you dial a Connection, the call is executed according to the Inbound Action set on a Connection. This Inbound Action is either:

  • default (bridge)

  • Call Flow

However, if a Connection has Call Flow attached, Inbound Action is changed to Call Flow and a call is running through actions defined in Call Flow instead. Call Flows are very flexible, you can set them up to bridge (transfer) a call to Connection or to play some speech from text before a transfer, or maybe send a call to a voicemail, you got it - possibilities are endless

Number

The other useful change to a Connection that you can easily make is attaching a Number to it, and we will discuss that in the following section 🤓 😊

It's very simple and it takes less than 2 minutes to get done on

To create a Connection, go to the Connections tab on VoIP Number () and click ADD. Fill in these 3 parameters and click ADD or press ENTER

SIP user is just a different name for an extension. This can be any text and it doesn't have to be a number. It must be a unique name on - a notification dialog will inform you if the name is already taken

As we said earlier you may want to create Connections only to execute . For example to play a text announcement to the call, play an audio file, collect digits (DTMF), or bridge a call to a Connection. In this case, you do not need to register to such a Connection from any SIP device and we call it virtual Connection 👻. It just defines what happens to a call by having a Call Flow attached (or voicemail enabled), no device is needed 😊

To dial Connection from a SIP device registered on simply call a SIP USER NAME associated with the Connection. To dial Connection from the telephony network you need a Number

By default new Connection has Inbound Action set to default (bridge). That means that by default a call is sent to the SIP device registered on to the Connection's SIP credentials and then to its Voicemail with audio transcription 📫📝, if the call was not answered
