[Asterisk-Dev] DTMF when transferring calls - not handled well?

[Bryan Field-Elliot]

Could you please send me your patch?

We have tried the Grandstream HT286, the Sipura 1001, and a LeadTek
device (not sure the model), and none of them appear to like how
Asterisk sends them DTMF digits via RFC2833. They just don't play the
digit for the analog device plugged into it.
