Call a callback on all agents of a specific type.
Since the container of CC core instances is private, and so are the items which the container contains, we have to provide an ao2_callback-like method so that a specific agent may be found or so that an operation can be made on all agents of a particular type. The first three arguments should be familiar to anyone who has used ao2_callback. The final argument is the type of agent you wish to have the callback called on.

This function creates a CC control frame payload, simulating the act of reading it from the nonexistent outgoing channel's frame queue. We then handle this simulated frame just as we would a normal CC frame which had actually been queued by the channel driver.

Make CCBS available in the case that ast_call fails.
One caveat is that this may only be used if generic monitoring is being used. The reason is that since Asterisk determined that the device was busy without actually placing a call to it, the far end will have no idea what call we are requesting call completion for if we were to send a call completion request.

Decide if a call to a particular channel is a CC recall.
As a quick example, let's say a call is placed to SIP/1000 and SIP/1000 is currently on the phone. The caller requests CCBS. SIP/1000 finishes his call, and so the caller attempts to recall. Now, the dialplan administrator has set up this second call so that not only is SIP/1000 called, but also SIP/2000 is called. If SIP/1000's channel were passed to this function, the return value would be non-zero, but if SIP/2000's channel were passed into this function, then the return would be 0 since SIP/2000 was not one of the original devices dialed.
This function will lock the channel as well as the list of monitors on the channel datastore, though the locks are not held at the same time. Be sure that you have no potential lock order issues here.
chan | The channel to check | |
[out] | core_id | If this is a valid CC recall, the core_id of the failed call will be placed in this output parameter |
monitor_type | Clarify which type of monitor type we are looking for if this is happening on a called channel. For incoming channels, this parameter is not used. |
0 | Either this is not a recall or it is but this channel is not part of the recall | |
non-zero | This is a recall and the channel in question is directly involved. |

int ast_cc_monitor_party_b_free | ( | int | core_id | ) |
Alert a caller that though the callee has become free, the caller himself is not and may not call back.
When an ISDN PTMP monitor senses that his monitored party has become available, he will request the status of the called party. If he determines that the caller is currently not available, then he will call this function so that an appropriate message is sent to the caller.
Yes, you just read that correctly. The callee asks the caller what his current status is, and if the caller is currently unavailable, the monitor must send him a message anyway. WTF?
This function results in the agent's party_b_free callback being called. It is most likely that you will not need to actually implement the party_b_free callback in an agent because it is not likely that you will need to or even want to send a caller a message indicating the callee's status if the caller himself is not also free.

int ast_cc_monitor_stop_ringing | ( | int | core_id | ) |
Alert a caller to stop ringing.
When an ISDN PTMP monitor becomes available, it is assumed that the agent will then cause the caller's phone to ring. In some cases, this is literally what happens. In other cases, it may be that the caller gets a visible indication on his phone that he may attempt to recall the callee. If multiple callers are recalled (since it may be possible to have a group of callers configured as a single party A), and one of those callers picks up his phone, then the ISDN PTMP monitor will alert the other callers to stop ringing. The agent's stop_ringing callback will be called, and it is up to the agent's driver to send an appropriate message to make his caller stop ringing.

Check if the incoming CC request is within the bounds set by the cc_max_requests configuration option.
If this is not called and a state change to CC_CALLER_REQUESTED is made, then the core will still not allow for the request to succeed. However, if done this way, it may not be obvious to the requestor why the request failed.

void ast_handle_cc_control_frame | ( | struct ast_channel * | inbound, | |

) |
Properly react to a CC control frame.
Unless we are ignoring CC for some reason, we will always call this function when we read an AST_CONTROL_CC frame from an outbound channel.
This function will call cc_device_monitor_init to create the new cc_monitor for the device from which we read the frame. In addition, the new device will be added to the monitor tree on the dialed_cc_interfaces datastore on the inbound channel.
If this is the first AST_CONTROL_CC frame that we have handled for this call, then we will also initialize the CC core for this call.

int ast_setup_cc_recall_datastore | ( | struct ast_channel * | chan, | |
const int | core_id | |||
) |
Set up a CC recall datastore on a channel.
This function must be called by the implementer once it has been detected that an inbound call is a cc_recall. After allocating the channel, call this function, followed by ast_cc_set_cc_interfaces_chanvar. While it would be nice to be able to have the core do this automatically, it just cannot be done given the current architecture.
