[Freeswitch-users] Using play_and_get_digits (or IVR) without a final delay

[Robert L Mathews]

Hi, I'm a new FreeSWITCH convert from asterisk. It's great software; 
thanks for making it.

I'm trying to play a sound file while listening for possible digits 
dialed (although in most cases callers will not be dialing anything).

If callers do start dialing an extension while the sound file is 
playing, I want them to be able to dial it slowly without any problems. 
So the inter-digit timeout should be, say, 2 seconds.

However, if people don't start dialing anything while the sound file is 
playing, I don't want any delay at the end of it.

I've tried play_and_get_digits with a 2000 timeout -- but that causes a 
2 second "dead air" pause at the end of the sound file if callers don't 
dial anything.

I've also tried using a trivial IVR menu to simulate this, but it has 
the same problem. Interestingly, it doesn't *look* like IVRs should have 
the problem, because they allow both "inter-digit-timeout" and "timeout" 
to be specified separately -- but at least in FreeSWITCH 1.0.4, a short 
"timeout" value always interrupts the dialing of digits, even if 
"inter-digit-timeout" is much longer.

Is there any way to play a sound file from the dial plan with a long 
inter-digit delay, but without any final delay if no digits are dialed?

Thanks for your time!
