[asterisk-users] 9 becomes 99 ? And other strangeness

[Eric "ManxPower" Wieling]

Turn off relaxdtmf in zapata.conf if that does not help play with the 
rxgain, if that does not help, play with the txgain.  If the volume is 
too loud or too soft on zap channels, Asterisk can sometimes miss or see 
double DTMF.
