Chapter1.Admin Guide

1.1.Overview

The Call Center module implements an inbound call center system with call flows (for queuing the received calls) and agents (for answering the calls).

The module implements the queuing system, the call distribution to agents, agents managements, CDRs for the calls, statistics on call distribution and agent's activity - basically everything except the media playback (for the queue). This part must be provided via a third party media server (FreeSwitch, Asterisk or others).

1.2.How it works

The main entities in the modules are the flows (queues) and agents.

1.2.1.DB tables

Each entity has a corresponding table in the database, for provisioning purposes - the cc_flows and cc_agents tables, see DB schema. Data is loaded at startup and cached into memory ; runtime reload is possible via the MI commands (see the cc_reload command in Exported MI Functions).

Additionally there is a table cc_cdrs for writing the CDRs - this operation is done in realtime, after the call in completed, covering all possible cases: call was dropped while in queue, call was rejected by agent, call was accepted by agent, call terminated with error - NOTE that a call may generate more than one CDR (like call rejected by agent A, and redistributed and accepted by agent B).

The cc_calls table is used to store ongoing calls, regardless it's state (in queue, to the agent, ended). It is populated at runtime by the module and queried at startup. This table should not be manually provisioned.

1.2.2.Call Flows

A flow is defined by a unique alphanumerical ID - the main attribute of a flow is the skill - the skill is a capability required by the flow for an agent to be able to answer the call ; the concept of skills is the link between the flows and the agents - telling what agents are serving what flows - the flows require a skill, while the agents provide a set of skills. Agents matching the required skill of a flow will automatically receive calls from that flow.

Additional, the flow has a priority - as agents may server multiple flows in the same time (based on skills), you can define priorities between the flows - if the flows has a higher priority, its calls will be pushed (in deliver to agents and queuing) in front of the calls from flows with a lower priority.

Configurable per flow, the module may do per-flow call dissuading; this means to redirect a call to another destination, if the queue/flow is overloaded:

  • if the number of calls already in the queue exceeds the diss_qsize_th threshold

  • if the estimated time to wait of the queue exceeds the diss_ewt_th threshold

  • if the call was waiting in the queue for longer than diss_onhold_th threshold

Optionally, the flow may define a prependcid - a prefix to be added to the CLI (Caller ID) when the call is delivered to the agents - as an agent may receive call from multiple flows, it is important for the user to see which was the queue a call was received.

In terms of media announcements, the flow defines the message_welcome (optional, to be played in the call, before doing anything with the call) and message_queue (mandatory, the looping message providing infinite on hold media IMPORTANT - this message must cycle and media server must never hung up on it. Both announcements are provided as SIP URIs (where the call has to be sent in order to get the playback).

The flow also has an optional max_wrapup time, which acts as an upper limit for the per-agent/global value (the flow forces a ceiling of the wrapup value for all its calls).

1.2.3.Agents

An agent is defined by a unique alphanumerical ID - the main attribute of an agent is its the set of skills and its SIP location. The set of skills will tell what calls to be received (from which flows, based on the skill matching); the location is a SIP URI where to call must be sent in order to be answered by the agent.

Additionally, the agent has a initial logstate - if he is logged in or not (being logged in is a must in order to receive calls). The log state may be changed at runtime via a dedicated MI command cc_agent_login, see Exported MI Functions.

There is an optional per-agent wrapup_time defined, saying the time interval for an agent before getting a new call from the system (after he finished a call). If no value is defined for the agent, the global wrapup_time will be used. Note that the resulting value may be upper limited by the per-flow max_wrapup_time if defined.

1.5.Exported Functions

1.5.1. cc_handle_call( flowID [,param])

This must be used only for initial INVITE requests - the function pushes the call to be handled by the call center module (via a certain flow/queue).

This function can be used from REQUEST_ROUTE.

Parameters:

  • flowID (string) - the ID of the flow to handle this call (push the call to that flow).

  • param (string, optional) - an opaque string to be passed as parameter to the "callcenter" and "agent" B2B scenarios. It is intended for custom integration of the call center module and it is 100% up to the script writer about the value and purpose of this parameter, OpenSIPS will not touch or interpret it.

The function returns TRUE back to the script if the call was successfully pushed and handled by the Call Center engine. IMPORTANT: you must not do any signaling on the call (reply, relay) after this point.

In case of error, FALSE is returned to the script with the following return codes:

  • -1 - unable to get the flow ID from the parameter;

  • -2 - unable to parse the FROM URI;

  • -3 - flow with FlowID not found;

  • -4 - no agents logged in the flow;

  • -5 - internal error;

Example1.30.cc_handle_call usage

...
if (is_method("INVITE") and !has_totag()) {
	if (!cc_handle_call("tech_support")) {
		send_reply(403,"Cannot handle call");
		exit;
	}
}
...

1.5.2. cc_agent_login(agentID, state)

This function sets the login (on or off) state for an agent.

This function can be used from REQUEST_ROUTE.

Parameters:

  • agentID (string) - the ID of the agent

  • state (int) - an integer value giving the new state - 0 means logged off, anything else means logged in.

Example1.31.cc_agent_login usage

...
# log off the 'agentX' agent
cc_agent_login("agentX",0);
...

(2) including any documentation-related commits, excluding merge commits. Regarding imported patches/code, we do our best to count the work on behalf of the proper owner, as per the "fix_authors" and "mod_renames" arrays in opensips/doc/build-contrib.sh. If you identify any patches/commits which do not get properly attributed to you, please submit a pull request which extends "fix_authors" and/or "mod_renames".

(3) ignoring whitespace edits, renamed files and auto-generated files
