Summary:                    Overlap dialing blocks
Description: 
The problem: when a channel is not connected and DTMF events arrive "too
fast", they get stored in the channel buffer until (a) sufficient time has
passed and (b) a voice frame has arrived.

Unfortunately, when you're in overlap dialing and the channel's audio is
not yet connected, there _is_ no voice frame, thus dialing blocks.

A quick fix is to surround wait_for_answer() with calls to set/clear the
AST_FLAG_END_DTMF_ONLY flag (patch attached).
