Greetings everyone,
Kia ora,
I am attempting to adjust the volume of a call using *Set(VOLUME)* in my
extensions.conf file. I am finding that*Set(VOLUME(TX)=x)*and
*S**et(VOLUME(RX)=y)*have no discernable effect on my endpoints (Snom
300 IP phones). I have tried setting x and y to -30, -10, -3, -2, -1, 0,
1, 2, 3, 4, 10, and 100 and there appears to be no change on the phone
volume. I can see that the Set(VOLUME) instruction is being executed on
the Asterisk CLI.
I just did the following on 13.5.0:
exten => 1002,1,Answer
exten => 1002,2,Set(VOLUME(tx)=10)
exten => 1002,3,Playback(demo-congrats)
From my D70 and confirmed the audio was ... louder/horrible.
Do you have any other endpoints you could test from?
I have also tried using *Set(CHANNEL(txgain)=x)* and
*Set(CHANNEL(rxgain)=y)* and those don't seem to have any effect either.

These aren't applicable to PJSIP.
I am using *PJSIP *and just upgraded to *Asterisk 13.5.0*. It wasn't
working on 13.4.0 either, but when I saw the release notes on 13.5 and
volume was addressed, I was hopeful that it might solve my problem for me.
So I have a couple of questions:
1) Am I using the correct functions in the dial plan to adjust volume?
It would be something like:
same => n,Set(VOLUME(TX)=3)
or
same =>n,Set(CHANNEL(rxgain)=0)
Yes, the VOLUME dialplan function should do the job.
2) If this is correct, what are the min/max values that I can use when
adjusting volume? I was digging around the source code and it looked
like maybe a min of -4 and max of +4 was expected - but I am unsure.
There is no enforced minimum/maximum. The value provided is in dB.
Cheers,
