Hi

I have a question about behavior of ReleaseAndAnswere().
If I am right, this function implements +CHLD=1 at command. Spec 22.030 says

Entering 1 followed by SEND     -              Releases all active calls (if any exist)
                                and accepts the other (held or waiting) call.

oFono is failing on this command when there are held and
active calls as there is only check if waiting call exists in
manager_release_and_answere().

Shouldn't ReleaseAndAnswere() release the active call and bring back the held
one in such situation?

There also could be a little more description of behavior for a case when we have
held and waiting calls saying that the waiting call will be answered and that held
won't be released.

Best regards
Tomasz Gregorek
