Summary:                    Local channel DTMF detection broken by 17370
Description: 
The patch for issue 17370 has broken DTMF detection when calling through a
local channel. Here is a dialplan to quickly reproduce this. Dial 3350
enter 4567 and you will hear goodbye. Dial 3351 and you will hit invalid
every time. Revert the patch for 17370 and dialing 3351 works.

exten => 3350,1,Goto(loopdtmf,s,1)
exten => 3351,1,Dial(Local/3350 at from-internal,300,TW)

[loopdtmf]

exten => s,n,GotoIf($[${LOOPNUM} = 4567]?good)
exten => s,n,Playback(invalid)
exten => s,n,Goto(repeat)
exten => s,n(good),Playback(goodbye)
exten => s,n,Hangup
