asterisk users - Oct 2006 - Query regarding Pulse Dialing at 20 pps

Hi,

I have a query regarding pulse dialing at 20 pps. 

An Analog Phone is directly connected to the FXS port of Asterisk PBX.
When the analog phone pulse-dials at 20 pps, the pulse digits were not
decoded correctly by Asterisk. For e.g. when the user dials a "2",
Asterisk decodes the pulse digit as "1". 

Does anyone know how this problem could be solved ?

Thank you.

Hi, 

Does anyone know how I could configure the make/break ratio of pulse 
dialing in Asterisk ?
