Traffic shaping IAX

[Gob]

Hi
I am trying to improve the call quality on our trixbox and have implemented traffic shaping on our pfS 1.2.3 box.
I have enabled VOIP optimisation and selected Asterisk and specified a bandwidth reservation.

My query is "Does the voip optimisation work with IAX traffic as well as SIP?"

thanks
Gordon

that i'm not sure of.  it is easy enough to just enter your trixbox IP address in the voip IP field and it won't matter :)

[Gob]

that I have done, However I assumed that only applies to certain ports that are defined in the traffic shaper as VOIP ports?

IAX is much simpler than SIP as it only uses TCP port 4569. I could add a manual rule for this port in the shaper, but would that then conflict with the voip optimisation rules if it already existed there?

No, if you put the "voip IP", it applies to all traffic wrt that host, AFAIK.  yes, for IAX2, you can prioritize UDP/4569 though.
