Devices and integrations

VoIP can be used on many different devices, such as a computer, tablet, mobile phone, and many more. This is helpful in that it reduces costs, and employees can work from anywhere in the world, so long as they have a broadband internet connection.

Odoo VoIP is SIP (Session Initiation Protocol) compatible, which means it can be used with any SIP compatible application.

This document covers the process of setting up Odoo VoIP across different devices and integrations.

Odoo is fully-integrated with all Odoo apps, allowing users to click into any app, and schedule a call as an activity in the chatter.


For example, in the CRM app, a user can click into an opportunity, and click on Activities in the chatter.

Next, they can choose Call, and under Due Date, they can select a date.

Once they click Save, an activity shows up in the chatter.

Should the Due Date be for today’s date, the activity shows up in the VoIP widget.

Odoo VoIP (tablet/mobile device)

The Odoo VoIP app can be used on tablets and mobile phones, through the Odoo Android or Apple IOS applications. Additionally, a mobile web browser can be used to access the database.


Odoo Android and Apple IOS applications are no longer being maintained by Odoo on the Android and Apple portals. This means Odoo support only handles limited scopes of Odoo Android or Apple IOS support tickets.


While outgoing calls can be placed using Odoo on a mobile device, be aware that Odoo is not a full VoIP application, and does not ring on incoming calls. If the user needs to be reachable on a mobile device at all times, an app, like Zoiper, should be used. Apps like that stay connected in the background at all times.

For more information, see this documentation: Zoiper Lite.

While in the mobile application on a mobile device/tablet, access the Odoo VoIP widget, by tapping on the 📞 (phone) icon in the upper-right corner. The widget appears in the lower-left corner.

When first making a call from the tablet using the mobile application, the user is prompted to Allow the database to use the microphone. Click Allow when prompted to continue with the call using the microphone.

This step is necessary, whether using the mobile Odoo application or web browser.

Allow the database to access the microphone.

Odoo then asks how to make the call. The two options are : VOIP or Phone (should the tablet be enabled for calling). Click the box next to Remember ? should this decision be the default moving forward.

Window prompt to choose whether to use VOIP or the devices phone to make the call.
