This article talks about a workaround that can help solve the issue with WhatsApp video calling/voice calling when ISDB is used. |
Scope |
FortiGate, 7.0.x. |
Solution |
Allowing the users behind the FortiGate to perform WhatsApp video calls/voice calls can be tricky sometimes, as the ports used for calling varies. FortiGate has an Internet database option that can be used as a destination for a granular outcome.

Despite the above policy, there could be some issues with WhatsApp calling (both video and voice). Meta edge servers are used by WhatsApp calls via VoIP STUN service (port 3478). Since these servers are widely used by other Meta services, can’t be moved to the Meta-WhatsApp object. In such case try adding ISDB-‘Meta-Other’ to the existing policy.
Note: Make sure the ports specified in the below article are allowed as a prerequisite: Technical Note: WhatsApp Voice Call is not working when connected to FortiGate. |
