Asterisk TOS=0x68 for SIP - How to match in pfsense QOS VOIP Queues?
I was having trouble getting the SIP traffic for the hosts in the alias I setup, VOIPERS, to route to the VOIP up/down queues. I had lowdelay set on the pfsense side. On the Asterisk side, under its SIP conf file, it used to support 'tos=lowdelay', but, now, it uses 'tos=0x68' (which is also being used by a lot of other SIP devices these days I read). Should I just "not care" and what about settings for Reliability and Throughput? And, is there some way to have pfsense recognize the SIP by 0x68?
I am completely new to traffic shaping (< 24 hours) but a fast learner! :-)
This is a diffserv value, another implementation to use the same bits in the header like the TOS field. Unfortunately pfSense can't handle these values atm. See http://en.wikipedia.org/wiki/Diffserv
