BBM Voice is compatible with the most common personal/home WiFi network configurations.  To initiate a BBM Voice chat simply connect to a WiFi access point, and from within any BBM chat, tap the BBM Voice icon or press your phone hard key whenever your contact shows available.

Note: Your contact must also be connected to a WiFi access point and the BBM voice icon will be green when they are available.

If you are experiencing difficulty making or receiving BBM Voice chats or you have received the “Your voice chat failed due to a problem with the network connection” message a firewall maybe in place.   Firewalls add an additional level of security to your connection by permitting and denying network traffic between devices on the internal network and the internet.  BBM Voice uses the following ports and porting forwarding must be enabled for the application to work on a traffic restricted network:

• 443 (TCP)
• 3478 (TCP)
• 3478 (UDP)
• 62148 to 62169 (UDP)
BBM Voice also communicates with the following addresses; therefore, they need to be white-listed:


For guidance on how to setup port forwarding, please contact your network administrator or refer to the documentation included with your router, firewall, or security software.
