[asterisk-ss7] Answer() is needed but it costs to the calling party while the extension is still ringing!

[Ercan Yücebas]

Dear All

Is there other ways to not answer the channel in the dialpla for an
inbound pstn call and just pass the signalling through and lets the sip
extension ringing? After 200 ok, sure we have to answer the ss7 channel.
With Answer() in first position of a dialplan, the calling party starts
to pay, without having been really connected!
