Connect cloud hosted PBX

The SIP Connector module permits connecting a cloud hosted PBX to Bitrix24.

Not more than 10 cloud PBXs can be connected to one account.

By saying cloud hosted PBX connection, we mean connecting PBX using Rest API or using SIP connector.

As configuring PBX connection using Rest API is mostly done in the app downloaded on Bitrix24 Market, you can learn how to connect your PBX in the app description or contact the app developer. This article is about connecting cloud hosted PBX using SIP connector.

Make sure that the cloud hosted PBX that you want to connect to Bitrix24 supports SIP protocol.

You have free minutes available to make outbound calls and test the functionality. The number of free minutes and the active license term is displayed on the Connection page in the Balance and Statistics section.

You can accept incoming calls at no cost via your Bitrix24 SIP PBX. But to make outgoing calls or forward calls using your SIP PBX, you will need to purchase the SIP connector.

Read more in the article - What is SIP connector?.
Here are some important points to consider:
  • You need to buy only one SIP-connector, no matter how many SIP PBXs you need to connect.

  • SIP-connector needs to be purchased separately and is not related to Telephony balance.

  • We do not recommend using the application and SIP connection from one provider at the same time. It can cause errors: duplicate calls in the call details, no "Answer" button, etc.


Connection configuration in Bitrix24

  1. Go to CRM > Add-ons > Telephony section, click Connection > Cloud PBX.

  2. Then click Connect cloud PBX.

  3. Fill out the form. Ask your provider for this information.

    • Connection name - an arbitrary name of the connection. This field is optional.

    • Server Address – this is the IP address of your PBX.

    • Login and Password – PBX access data.

    Some PBXs need the configuration of additional parameters, such as:

    • Log in as user - enter the data from auth user field of PBX settings.

    • Proxy server - enter the data from sip outbound proxy field of PBX settings.

  4. Click Save and configure the connection settings.


Cloud hosted PBX settings

PBX connection is not completed in an instant but undergoes some steps. Here you can see the meaning of each connection status:

  • In process - connection is processing. You will be able to accept inbound calls in several minutes.

  • Receiving data - data about the current status is being received. Please wait.

  • Error - an error has occurred during the connection. Please make sure that the connection parameters you indicated are correct.

After getting the Success status, you can proceed with the number settings.

Firewall settings in the local network

By default, the following ports are used:

  • For calls from a browser: 443 TCP, 3478 TCP/UDP, 8000-48000 UDP.

  • For calls from a SIP device: 5060 TCP/UDP, 3478 TCP/UDP, 8000-48000 UDP.

Normally, it is important for SIP to have outbound traffic permitted (e.g., from PBX) and inbound connections will work automatically. RTP is normally used as UDP (so that packets can be lost without impeding data transmission).

The ports themselves can be set up in the PBX properties: the ports that are indicated there must also be open in Firewall.
