I have read through a bunch of posts talking about QOS and almost all that I have seen were directed at the PBX side. I have a PBX in a hosting center with very high speed internet. My issue is some of my clients have crappy broadband services with limited upload speeds in the order of 10Mbps. With the computer traffic on the same line even minimal office work frequently interferes with voice quality. I have many offices on better services like FTTI and only my broadband users have issues. I am looking for more information on what ports I should be enabling on the firewall QOS settings? Although any information is better than none I am hoping for some direction specific to my sonic wall customers.
I am only concerned with sending QOS settings from the perspective of the firewall as I have plenty of download speed and I believe my issue is purely an upload issue. I can see some of the phones in EPM that typically have response times in the order of 50-60ms often go above 100ms and in a few cases as high as 1000ms. Obviously this is an issue as some of the phones deregister and then call flow suffers, people randomly cant use their phones other times calls go straight to VM.
SO unless I am misunderstanding something I want all traffic to my pbx to be given a priority. I am somewhat confused though about the call flow and once a call is in progress does the phone talk directly to my SIP provider or does it still go through the pbx? Do I need to add my SIP provider to the QOS too?
