We have an issue with FortiGate SDWAN (running 7.0.10) when calling with Teams to an external number and failing over from WAN1 to WAN2. When we do a direct Teams call between Teams clients the call remains active when doing a failover from WAN1 to WAN2. But a call from a Teams client to an external number disconnects when failing over from WAN1 to WAN2.
Does anyone have the same experience? Is it maybe related to a SIP timer within Microsoft?
