- Parameters:
-
o Outgoing call channel list. num Incoming call channel cause accumulation peerflags Dial option flags single TRUE if there is only one outgoing call. caller_entertained TRUE if the caller is being entertained by MOH or ringback. to Remaining call timeout time. forced_clid OPT_FORCECLID caller id to send stored_clid Caller id representing the called party if needed
XXX this code is highly suspicious, as it essentially overwrites the outgoing channel without properly deleting it.
- Todo:
- eventually this function should be intergrated into and replaced by ast_call_forward()

* offered during a ringing message. Let's say that party A calls
* parties B, C, and D. B and C do not support CC requests, but D
* does. If we were to receive a ringing notification from B before
* the others, then we would end up sending a ringing message to
* A with no CCNR offer present.
*
* The approach that we have taken is that if we receive a ringing
* response from a party and no CCNR offer is present, we need to
* wait. Specifically, we need to wait until either a) a called party
* offers CCNR in its ringing response or b) all called parties have
* responded in some way to our call and none offers CCNR.
*
* The drawback to this is that if one of the parties has a delayed
* response or, god forbid, one just plain doesn't respond to our
* outgoing call, then this will result in a significant delay between
* when the caller places the call and hears ringback.
*
* Note also that if CC is disabled for this call, then it is perfectly
* fine for ringing frames to get sent through.
