Traffic shaping policy for VoIP

Hi,

Need advice from somebody who knows well about VoIP.

Our VoIP phones works fine as long we allow all traffic through the firewall :(

We don't use any PBX server, the phones connect directly to the provider. SIP as been disabled as recommended by the provider. If I use the #Default_Network_Policy, a few phones loose connection with the provider. A view of the log (198.41.28.71 belongs to our VoIP provider.):

Also,here the VoIP firewall I was trying earlier to implement to set the highest priority for VoIP communications:

The highest voice quality codec used is G.711. Am I doing anything wrong? Can "individual" bandwidth usage type be used for IP addresses filtered by this FW rule? Or is it only for configured Users?

Tks

I've called at least 4 times Sophos support today and nobody knows how to deal with VoIP. They know what's a VoIP phone and that's it.

If I ask "what's the best practice regarding firewall rules for VoIP?", they have no clue!

Am I the only person using VoIP phones in this word? :O

Seems like you are using a Softphone app to make your calls. You are adding a traffic shaping policy to an app... I do this for devices which is a bit different.

Not sure then why you are using Application Control (VOIP). Can you explain please? :)

Thanks

Because VoIP (protocol) is an application not a web access. You are not using the http proxy to manage your phone access.
