Thanks for your answer! You are right and first option what I am
looking for. I have asked support staff and sending back DTMF on open
channel does not help.

Unfortunately I am not expert on this topic as well but second option
is not good for us. The question is how good Asterisk's Q.SIG
implementation for this task.

Often we have more than 15 calls at same time and that is why first
option is not acceptable.
