[Asterisk-Users] Wifi UT Starcom F1000: Raising Audio volume Level via asterisk?

[Bruno.Voigt at ic3s.de]

Hi all,

I' m currently testing a Wifi UT Starcom F1000 and for my taste
even with the audio volume level even on max. setting,
the speaker is not loud enogh.

Is there a way to raise the audio-level 
specifically for a concrete SIP device via a sip.conf setting or something 
like that ??

TIA,
Bruno
