Much needed was a way to assign id to objects on creation, and much change was necessary to accomplish it. Channel uniqueids and linkedids are split into separate string and creation time components without breaking linkedid propgation. This allowed the uniqueid to be specified by the user interface - and those values are now carried through to channel creation, adding the assignedids value to every function in the chain including the channel drivers. For local channels, the second channel can be specified or left to default to a ;2 suffix of first. In ARI, bridge, playback, and snoop objects can also be created with a specified uniqueid. Along the way, the args order to allocating channels was fixed in chan_mgcp and chan_gtalk, and linkedid is no longer lost as masquerade occurs.

|
|
*
|
|
* Call completion complicates the logic used here. CCNR is typically
|
|
* 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.
