Voice messages shorter than 5 seconds aren't stored

Hi,

I noticed that messages shorter than 5 seconds aren't stored by AskoziaPBX. Here is the log that I got for a 4-seconds message:

Apr 30 22:12:31 asterisk[1381]: VERBOSE[29773]: -- Recording was 4 seconds long but needs to be at least 5 - abandoning

I understand that this behavior is on purpose. However, it's a problem for me, as I receive sometimes real messages, which are shorter than 5 seconds (3 or 4 seconds, for example when the caller say something "Hi, this is Bob, call me."). The person thinks that the message is stored, but I won't get it ever.

Would be nice to decrease the limit of message length to 2 or 3 seconds, or (much better) make this setting configurable via the GUI.
