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. ; ;accept: If an interface is set to "accept," 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. ; ;cc_agent_dialstring=
