[Asterisk-Users] DTMF not sending properly via IAX

[Mark Edwards]

Hi Tony
 I am having a similar issue to you - from the 'other' direction in that 
when I connect to * via IAX2 the DTMF is being ignored. I am running HEAD at 
the moment. 
 (and for the benefit of another subscriber so that they don't have to 
invoke their autoresponder I acknowlege that DTMF is sent out of band over 
IAX...)

 Does this bear any relation?
