Is there a way to receive SIP INFO messages in FS?  Ideally without events but if there is no way, then with events may be OK.

For reference, I currently do it by having the other side send a DTMF tone  via INFO, catching it with bind_digit_action and then checking the sip_info_h headers for the payload.

But I was wondering if there is a way to do it with a straight INFO messages rather than a DTMF.
