Is there a way to get answer confirmation via IAX and not only via
ZAP? We get our outbound service via an IAX trunk to our provider so
we aren't in control of their ZAP configs, but ideally we'd like to
be able to achieve the answer confirmation functionality regardless,
especially in the case of follow-me that dials SIP and IAX extensions
simultaneously when the IAX dials a cell phone that goes to
voicemail. Without the ability to confirm the answer, the call is
completed when the cell phone voicemail picks up the call, which
sucks :(
