[Asterisk-Users] rx/txgain per device?

[Dan Elder]

Is it possible to adjust the rx/txgain values per device? I have a mishmash
of different phones (soft phones & sip hard phones) and each of them sound
different w/the same rx/txgain settings. Is there any way to adjust these
via asterisk? I'm having the most difficulty with sjphone & these zultys
zip2 phones, vol is right on one, but way off on the other.

Thx again...
