[Freeswitch-dev] start_dtmf detects dtmf as may times per dtmf as many times start_dtmf issued.

[Anton VG]

Just noted that my ESL get as may DTMF events per single keypress as,
many times I issued start_dtmf on the uuid.

it means if I do:

execute('start_dtmf')
execute('start_dtmf')

I get the same DTMF event twice.

Is that expected behavior? Logically, it supposed to to trigger detection on/off
