Perhaps they can even include the topic and you can always reply that you
can 't [don't want to] get back to them.

Regarding this, Anveo supports Early Media (= the ring tone = audio that is played back before the call in answered = the caller is not charged for the call while he is hearing this media).

Early Media even supports key presses. So, for example with a call flow like the attached picture the ring tone is replaced. If the callers press 0 they will hear the song "remix". If they press 1 to 9 they will hear the song "original". And while doing this and hearing these songs they are not charged for the call (until you answer the phone).

This can also be a good way to playback a recorded voice message.
