Audio calls drops frequently when connected to VPN
frequent call drops when connected on a VPN.
Please bring this issue with your IT Network team. The recommended solution is to implement VPN split tunneling.
details are in this article: https://docs.microsoft.com/en-us/microsoftteams/prepare-network#:~:text=Split%20tunneling%20means%20that%20traffic,devices%20and%20the%20organizations%20network.
We recommend that you provide an alternate path for Teams traffic that bypasses the virtual private network (VPN), commonly known as [split-tunnel VPN](https://docs.microsoft.com/windows/security/identity-protection/vpn/vpn-routing). Split tunneling means that traffic for Microsoft 365 or Office 365 doesn't go through the VPN but instead goes directly to Microsoft 365 or Office 365. Bypassing your VPN will have a positive impact on Teams quality, and it reduces load from the VPN devices and the organization's network. To implement a split-tunnel VPN, work with your VPN vendor.
Other reasons why we recommend bypassing the VPN:
VPNs are typically not designed or configured to support real-time media.
Some VPNs might also not support UDP (which is required for Teams).
VPNs also introduce an extra layer of encryption on top of media traffic that's already encrypted.
Connectivity to Teams might not be efficient due to hair-pinning traffic through a VPN device.
Are there suggestions for this?
