Detailed Description

True call queues with optional send URL on answer.

Author:

Mark Spencer <markster@digium.com>

• Config in ACD - Queue system configuration queues.conf

Development notes

Note:

2004-11-25: Persistent Dynamic Members added by: NetNation Communications (www.netnation.com) Kevin Lindsay <kevinl@netnation.com>

Each dynamic agent in each queue is now stored in the astdb. When asterisk is restarted, each agent will be automatically readded into their recorded queues. This feature can be configured with the 'persistent_members=<1|0>' setting in the '[general]' category in queues.conf. The default is on.

Note:

2004-06-04: Priorities in queues added by inAccess Networks (work funded by Hellas On Line (HOL) www.hol.gr).

These features added by David C. Troy <dave@toad.net>:

• Per-queue holdtime calculation
• Estimated holdtime announcement
• Position announcement
• Abandoned/completed call counters
• Failout timer passed as optional app parameter
• Optional monitoring of calls, started when call is answered

Patch Version 1.07 2003-12-24 01

Added servicelevel statistic by Michiel Betel <michiel@betel.nl> Added Priority jumping code for adding and removing queue members by Jonathan Stanton <asterisk@doilooklikeicare.com>

Fixed to work with CVS as of 2004-02-25 and released as 1.07a by Matthew Enger <m.enger@xi.com.au>

Enumeration Type Documentation

anonymous enum

Please read before modifying this file.

There are three locks which are regularly used throughout this file, the queue list lock, the lock for each individual queue, and the interface list lock. Please be extra careful to always lock in the following order 1) queue list lock 2) individual queue lock 3) interface list lock This order has sort of "evolved" over the lifetime of this application, but it is now in place this way, so please adhere to this order!

Enumerator:

Note:

Should be called with the "queues" container locked.

Note:

Load from realtime before taking the "queues" container lock, to avoid blocking all queue operations while waiting for the DB.

This will be two separate database transactions, so we might see queue parameters as they were before another process changed the queue and member list as it was after the change. Thus we might see an empty member list when a queue is deleted. In practise, this is unlikely to cause a problem.

The starting point for all queue calls.

The process involved here is to 1. Parse the options specified in the call to Queue() 2. Join the queue 3. Wait in a loop until it is our turn to try calling a queue member 4. Attempt to call a queue member 5. If 4. did not result in a bridged call, then check for between call options such as periodic announcements etc. 6. Try 4 again unless some condition (such as an expiration time) causes us to exit the queue.

	)			[static]

Log an attended transfer when a queue caller channel is masqueraded.

When a caller is masqueraded, we want to log a transfer. Fixup time is the closest we can come to when the actual transfer occurs. This happens during the masquerade after datastores are moved from old_chan to new_chan. This is why new_chan is referenced for exten, context, and datastore information.

At the end of this, we want to remove the datastore so that this fixup function is not called on any future masquerades of the caller during the current call.

Part 2 of ring_one.

Does error checking before attempting to request a channel and call a member. This function is only called from ring_one(). Failure can occur if:

• Agent on call
• Agent is paused
• Wrapup time not expired
• Priority by another queue

Return values:

	1	on success to reach a free agent
	0	on failure to get agent.

Place a call to a queue member.

Once metrics have been calculated for each member, this function is used to place a call to the appropriate member (or members). The low-level channel-handling and error detection is handled in ring_entry

Return values:

	1	if a member was called successfully
	0	otherwise

		const char *	agi,
		const char *	macro,
		const char *	gosub,
		int	ringing
	)			[static]

A large function which calls members, updates statistics, and bridges the caller and a member.

Here is the process of this function 1. Process any options passed to the Queue() application. Options here mean the third argument to Queue() 2. Iterate trough the members of the queue, creating a callattempt corresponding to each member. During this iteration, we also check the dialed_interfaces datastore to see if we have already attempted calling this member. If we have, we do not create a callattempt. This is in place to prevent call forwarding loops. Also during each iteration, we call calc_metric to determine which members should be rung when. 3. Call ring_one to place a call to the appropriate member(s) 4. Call wait_for_answer to wait for an answer. If no one answers, return. 5. Take care of any holdtime announcements, member delays, or other options which occur after a call has been answered. 6. Start the monitor or mixmonitor if the option is set 7. Remove the caller from the queue to allow other callers to advance 8. Bridge the call. 9. Do any post processing after the call has disconnected.

Parameters:

[in]	qe	the queue_ent structure which corresponds to the caller attempting to reach members
[in]	options	the options passed as the third parameter to the Queue() application
[in]	announceoverride	filename to play to user when waiting
[in]	url	the url passed as the fourth parameter to the Queue() application
[in,out]	tries	the number of times we have tried calling queue members
[out]	noption	set if the call to Queue() has the 'n' option set.
[in]	agi	the agi passed as the fifth parameter to the Queue() application
[in]	macro	the macro passed as the sixth parameter to the Queue() application
[in]	gosub	the gosub passed as the seventh parameter to the Queue() application
[in]	ringing	1 if the 'r' option is set, otherwise 0

static int wait_our_turn	(	struct queue_ent *	qe,
		int	ringing,
		enum queue_result *	reason
	)			[static]

The waiting areas for callers who are not actively calling members.

This function is one large loop. This function will return if a caller either exits the queue or it becomes that caller's turn to attempt calling queue members. Inside the loop, we service the caller with periodic announcements, holdtime announcements, etc. as configured in queues.conf

Return values:

	0	if the caller's turn has arrived
	-1	if the caller should exit the queue.
