asterisk users - Dec 2003 - Trouble with AGI and SAY DIGITS and WAIT FOR DIGIT using PHP

Hi there,

AGI is partially not working for me with SAY DIGITS, SAY NUMBER, WAIT FOR 
DIGITS etc. It appears that result is always one for any function that 
looks for user input, regardless of which key was pressed. Playing sound 
is only possible using EXEC. This applies to two * servers with RH 7.2 
and RH 7.3 and very recent CVS. Any suggestion or tips about where I 
goofed?

Thanks, Philipp
