VOIP Over VPN was created by pepps1976
Hi All

I am using Draytek 2700 VG routers connected over VPN's to our main network, Each remote site has a hardware phone that connects to the main PBX over the VPN, is there a way i could dedicate a certain amount of bandwidth to the phone, because at the moment if the user is on the phone and he/She recieves an email the voice degrades and cuts out.

Thanks for any help

John

Similar situation with 2820 routers. Can you do QOS on a VPN link ??

On the 2700 series, no, since those don't support QoS, but if your main router supports QoS, then you can set up VPN classes for in & out traffic using the remote subnet IPs in the class settings.
This setup guide is for an old router but it should still be partially applicable:

Thanks for the help. I think that I am right in saying that the only problem with this is that it applies to ANY VPN traffic and doesn't differentiate between say VOIP or HTTP ?
