We have recently opened a branch office for developers to work out of. The guys there all have Aastra VoIP 'hard' phones on their desks.
The main office and branch offices are linked together via a VPN (using two Sonicwall Firewalls) the VoIP PBX we have is a Trixbox installation, interfacing to 4 PSTN lines.
Most of the time this setup works great, but if someone opens a file on a server at the 'other' end of the link the call quality drops off.
Is there some easy (and cheap) way we can make the VoIP traffic a higher priority?
Best Answer
SonicWall devices have QoS configuration options in the Enhanced OS version. We use this internally to prioritize VoIP and Citrix traffic on our VPN tunnels. I would think this would be your best option since it utilizes existing hardware.
