VOIP delay issues

[ariel_jesus237]

I have succesfully used voip in OpenArena, I am able to hear my friend and he can hear me but I am noticing a 5 +/- second delay and was wondering if there was any variable or server setting I could use to fix this problem. Another thing is the volume of the recordings is a bit on the low side and tweaking with cl_voipCaptureMult and cl_voipDefaultGain didn't seem to change anything. We tried lowering the sound effects on the game but it also lowered the voip volume. I'm currently using these settings:

sv_voip "1"

seta cl_voip "1"
seta cl_voipCaptureMult "2.0"
seta cl_voipDefaultGain "1.5"
seta cl_voipGainDuringCapture "1"
seta cl_voipSendTarget ""
seta cl_voipShowMeter "1"
seta cl_voipUseVAD "1"
seta cl_voipVADThreshold "0"

Any help is appreciated.

I've been told that /rate 25000 should be set while using the build in voip.

And the servers maxrate must be that or higher too, else it won't work anyway.
