[general]
|
|
; There is only a single option that may be defined in this file.
|
|
; The cc_max_requests option is a global limit on the number of
|
|
; CC requests that may be in the Asterisk system at any time.
|
|
;
|
|
;cc_max_requests = 20

|
|
;============================================
|
|
; PLEASE READ THIS!!!
|
|
; The options described below should NOT be
|
|
; set in this file. Rather, they should be
|
|
; set per-device in a channel driver
|
|
; configuration file.
|
|
; PLEASE READ THIS!!!
|
|
;===========================================
|
|
;
|
|
;---------------------------------------------------------------------
|
|
; Timers
|
|
;---------------------------------------------------------------------
|
|
;There are three configurable timers for all types of CC: the
|
|
;cc_offer_timer, the ccbs_available_timer, and the ccnr_available_timer.
|
|
;In addition, when using a generic agent, there is a fourth timer,
|
|
;the cc_recall_timer. All timers are configured in seconds, and the
|
|
;values shown below are the defaults.
|
|
;
|
|
;When a caller is offered CCBS or CCNR, the cc_offer_timer will
|
|
;be started. If the caller does not request CC before the
|
|
;cc_offer_timer expires, then the caller will be unable to request
|
|
;CC for this call.
|
|
;
|
|
;cc_offer_timer = 20
|
|
;
|
|
;Once a caller has requested CC, then either the ccbs_available_timer
|
|
;or the ccnr_available_timer will run, depending on the service
|
|
;requested. The reason why there are two separate timers for CCBS
|
|
;and CCNR is that it is reasonable to want to have a shorter timeout
|
|
;configured for CCBS than for CCNR. If the available timer expires
|
|
;before the called party becomes available, then the CC attempt
|
|
;will have failed and monitoring of the called party will stop.
|
|
;
|
|
;ccbs_available_timer = 4800
|
|
;ccnr_available_timer = 7200
|
|
;
|
|
; When using a generic agent, the original caller is called back
|
|
; when one of the original called parties becomes available. The
|
|
; cc_recall_timer tells Asterisk how long it should let the original
|
|
; caller's phone ring before giving up. Please note that this parameter
|
|
; only affects operation when using a generic agent.
|
|
;
|
|
;cc_recall_timer = 20
|
|
;---------------------------------------------------------------------
|
|
; Policies
|
|
;---------------------------------------------------------------------
|
|
; Policy settings tell Asterisk how to behave and what sort of
|
|
; resources to allocate in order to facilitate CC. There are two
|
|
; settings to control the actions Asterisk will take.
|
|
;
|
|
; The cc_agent_policy describes the behavior that Asterisk will
|
|
; take when communicating with the caller during CC. There are
|
|
; three possible options.
|
|
;
|
|
;never: Never offer CC to the caller. Setting the cc_agent_policy
|
|
; to this value is the way to disable CC for a call.
|
|
;
|
|
;generic: A generic CC agent is one which uses no protocol-specific
|
|
; mechanisms to offer CC to the caller. Instead, the caller
|
|
; requests CC using a dialplan function. Due to internal
|
|
; restrictions, you should only use a generic CC agent on
|
|
; phones (i.e. not "trunks"). If you are using phones which
|
|
; do not support a protocol-specific method of using CC, then
|
|
; generic CC agents are what you should use.
|
|
;
|
|
;native: A native CC agent is one which uses protocol-specific
|
|
; signaling to offer CC to the caller and accept CC requests
|
|
; from the caller. The supported protocols for native CC
|
|
; agents are SIP, ISDN ETSI PTP, ISDN ETSI PTMP, and Q.SIG
|
|
;cc_agent_policy=never
|
|
;
|
|
; The cc_monitor_policy describes the behavior that Asterisk will
|
|
; take when communicating with the called party during CC. There
|
|
; are four possible options.
|
|
;
|
|
;never: Analogous to the cc_agent_policy setting. We will never
|
|
; attempt to request CC services on this interface.
|
|
;
|
|
;generic: Analogous to the cc_agent_policy setting. We will monitor
|
|
; the called party's progress using protocol-agnostic
|
|
; capabilities. Like with generic CC agents, generic CC
|
|
; monitors should only be used for phones.
|
|
;
|
|
;native: Analogous to the cc_agent_policy setting. We will use
|
|
; protocol-specific methods to request CC from this interface
|
|
; and to monitor the interface for availability.
|
|
;
|
|
;always: If an interface is set to "always," then we will accept
|
|
; protocol-specific CC offers from the caller and use
|
|
; a native CC monitor for the remainder of the CC transaction.
|
|
; However, if the interface does not offer protocol-specific
|
|
; CC, then we will fall back to using a generic CC monitor
|
|
; instead. This is a good setting to use for phones for which
|
|
; you do not know if they support protocol-specific CC
|
|
; methodologies.
|
|
;cc_monitor_policy=never

|
|
;---------------------------------------------------------------------
|
|
; Limits
|
|
;---------------------------------------------------------------------
|
|
;
|
|
; The use of CC requires Asterisk to potentially use more memory than
|
|
; some administrators would like. As such, it is a good idea to limit
|
|
; the number of CC requests that can be in the system at a given time.
|
|
; The values shown below are the defaults.
|
|
;
|
|
; The cc_max_agents setting limits the number of outstanding CC
|
|
; requests a caller may have at any given time. Please note that due
|
|
; to implementation restrictions, this setting is ignored when using
|
|
; generic CC agents. Generic CC agents may only have one outstanding
|
|
; CC request.
|
|
;
|
|
;cc_max_agents = 5
|
|
;
|
|
; The cc_max_monitors setting limits the number of outstanding CC
|
|
; requests can be made to a specific interface at a given time.
|
|
;
|
|
;cc_max_monitors = 5
|
|
;
|
|
;---------------------------------------------------------------------
|
|
; Other
|
|
;---------------------------------------------------------------------
|
|
;
|
|
; When using a generic CC agent, the caller who requested CC will be
|
|
; called back when a called party becomes available. When the caller
|
|
; answers his phone, the administrator may opt to have a macro run.
|
|
; What this macro does is up to the administrator. By default there
|
|
; is no callback macro configured.
|
|
;
|
|
;cc_callback_macro=
|
|
;
|
|
; When using an ISDN phone and a generic CC agent, Asterisk is unable
|
|
; to determine the dialstring that should be used when calling back
|
|
; the original caller. Furthermore, if you desire to use any dialstring-
|
|
; specific options, such as distinctive ring, you must set this
|
|
; configuration option. For non-ISDN phones, it is not necessary to
|
|
; set this, since Asterisk can determine the dialstring to use since
|
|
; it is identical to the name of the calling device. By default, there
|
|
; is no cc_agent_dialstring set.
