[arm-allstar] Low Audio Level from Zoiper into node, out RF

[no1pc at yahoo.com]

Is there any way to increase/adjust the audio level coming from iax/Zoiper?
I have somewhat low audio from the Android version, which improved slightly turning off the AGC at the droid App.
I have extremely low audio from the iPhone app.
Sadly thinking that audio adjustments of the node-radio might have to reference the iax connections first, then adjust most likely down, the radio source level in USB config.  That changes things considerably as what WOULD be a standard level set from iax sources?
