QoS - Is the traffic really prioritized or is it just guaranteed bandwidth?

Question

Hello, 
 
 I would like to prioritize our telephony traffic (SIP, VoIP, some telephone-system specific ports) in our network. 
 Our network bandwidth is not fully utilizied but I want to have this kind of traffic treated with priority. 
 
 Does the guarantee of bandwith (which I can define in Bandwith Pools tab) also means the traffic itself will be prioritized or is it simply to allocate/reserve the bandwith in the case of a bottleneck? In case it is only to allocate the bandwidth: How can I prioritize the traffic?

Hey UTMaddict You can say that, as features like prioritizing, Latency, Jitter and Packet loss are lacking but you can migrate to Sophos Firewall which fulfills all the criteria mentioned.

Hello UTMaddict , Thank you for reaching out to the community, Under the Interface & Routing > Quality of Service (QoS) > Traffic Selectors > Add New Traffic selector . Here you you can define how this traffic gets handled by QoS, like limiting the overall bandwidth or guarantee a certain amount of minimum bandwidth Where as under the bandwidth pools you can define and manage bandwidth pools for bandwidth management, with a bandwidth pool, you reserve a guaranteed bandwidth for a specific outgoing traffic type, optionally limited by a maximum bandwidth limit. So I would not say it as traffic prioritizing but guaranteed bandwidth. Hope this clears your doubt.
