   i also try zoiper 2.13 & 2.14 with iax2 to test DTMF problem. still
using asterisk 1.4.18 with your patch. i press the key fast and sometimes
asterisk recognize the key sequence incorrectly. i found the dtmf duration
would be "0" ms if everything is correct. but when problem occurs, it would
become some random value. i don't if it's the problem of asterisk or
zoiper. problem log like below:
