We are having an issue where users, using our VPN connection, with the Fortinet VPN client and using the Mitel Connect software do not get the audio portion of a phone call. Neither side of the call can hear each other. The this feature with "soft phone" works, when the computer is internal and not making use of the VPN. I don't know if it is a setting in the Fortigate or an issue with the Mitel software.

What are the best practices and settings for VoIP calls through the firewall ?

I'm sorry if this is being double posted.

We are having the same issue using SSL-VPN on a FortiGate 301E and Mitel Connect. It appears that the UDP packets that carries the audio for Mitel Connect is not passing through the VPN. I wonder if the UDP packets can not be encrypted therefore it is not allow to pass through the VPN. Is the a way to have UDP pass through a SSL-VPN or would an IPsec VPN work better? Thanks.
