Traffic shaping policy for VoIP

Speatech

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
