[Freeswitch-users] Httapi playback: input-timeout

Tue Aug 13 14:01:07 MSD 2013

Hi. 

I setup an ivr using httapi and I've got a strange behaviour with input-timeout and digit-timeout attributes. 

The ivr xml is: 

<?xml version="1.0"?> 
<document type="text/freeswitch-httapi"> 
<work> 
<playback file="ivr/ivr-please_enter_the_number_where_we_can_reach_you.wav" name="FluentIvrDigitInput" terminators="#" input-timeout="10000" digit-timeout="5000"> 
<bind action="--my_bind_action_url--">~^\d+#</bind> 
</playback> 
<continue action="--my_continue_action--"/> 
</work> 
</document> 

With no input, t he timeout triggers after 10s but I was expecting 5s according to digit-timeout. 
The relevant log of the call is:

With a single digit input, the timeout triggers after 5s: i was expecting 10s (according to input-timeout). 
The log follows:

With a multi-digit input, the timeout triggers after 10s from the end of playback (according to input-timeout). I was expecting a 10s timeout after each digit.

According to Freeswitch wiki, t hese are the definitions of input-timeout and digit-timeout attributes: 
digit-timeout       : Pause to wait for digits after file plays (when input bindings are present)
input-timeout       : Pause to wait for more digits in a multi-digit input 

However the input-timeout acts as the maximum time the user has to enter the total input digits after the end of playback while the digit-timeout seems to be "ignored" when input-timeout is present. 

What am I missing? 

I'm using the latest stable version of freeswitch (1.2.12). 

Thank you for your help.
