9 ; There is only a single option that may be defined in this file.
10 ; The cc_max_requests option is a global limit on the number of
11 ; CC requests that may be in the Asterisk system at any time.
16 ;============================================
18 ; The options described below should NOT be
19 ; set in this file. Rather, they should be
20 ; set per-device in a channel driver
23 ;===========================================

27 ;---------------------------------------------------------------------
28 ;There are three configurable timers for all types of CC: the
29 ;cc_offer_timer, the ccbs_available_timer, and the ccnr_available_timer.
30 ;In addition, when using a generic agent, there is a fourth timer,
31 ;the cc_recall_timer. All timers are configured in seconds, and the
32 ;values shown below are the defaults.
34 ;When a caller is offered CCBS or CCNR, the cc_offer_timer will
35 ;be started. If the caller does not request CC before the
36 ;cc_offer_timer expires, then the caller will be unable to request
41 ;Once a caller has requested CC, then either the ccbs_available_timer
42 ;or the ccnr_available_timer will run, depending on the service
43 ;requested. The reason why there are two separate timers for CCBS
44 ;and CCNR is that it is reasonable to want to have a shorter timeout
45 ;configured for CCBS than for CCNR. If the available timer expires
46 ;before the called party becomes available, then the CC attempt
47 ;will have failed and monitoring of the called party will stop.
49 ;ccbs_available_timer = 4800
50 ;ccnr_available_timer = 7200
52 ; When using a generic agent, the original caller is called back
53 ; when one of the original called parties becomes available. The
54 ; cc_recall_timer tells Asterisk how long it should let the original
55 ; caller's phone ring before giving up. Please note that this parameter
56 ; only affects operation when using a generic agent.
59 ;---------------------------------------------------------------------
61 ;---------------------------------------------------------------------
62 ; Policy settings tell Asterisk how to behave and what sort of
63 ; resources to allocate in order to facilitate CC. There are two
64 ; settings to control the actions Asterisk will take.
66 ; The cc_agent_policy describes the behavior that Asterisk will
67 ; take when communicating with the caller during CC. There are
68 ; three possible options.
70 ;never: Never offer CC to the caller. Setting the cc_agent_policy
71 ; to this value is the way to disable CC for a call.
73 ;generic: A generic CC agent is one which uses no protocol-specific
74 ; mechanisms to offer CC to the caller. Instead, the caller
75 ; requests CC using a dialplan function. Due to internal
76 ; restrictions, you should only use a generic CC agent on
77 ; phones (i.e. not "trunks"). If you are using phones which
78 ; do not support a protocol-specific method of using CC, then
79 ; generic CC agents are what you should use.
81 ;native: A native CC agent is one which uses protocol-specific
82 ; signaling to offer CC to the caller and accept CC requests
83 ; from the caller. The supported protocols for native CC
84 ; agents are SIP, ISDN ETSI PTP, ISDN ETSI PTMP, and Q.SIG
85 ;cc_agent_policy=never
87 ; The cc_monitor_policy describes the behavior that Asterisk will
88 ; take when communicating with the called party during CC. There
89 ; are four possible options.
91 ;never: Analogous to the cc_agent_policy setting. We will never
92 ; attempt to request CC services on this interface.
94 ;generic: Analogous to the cc_agent_policy setting. We will monitor
95 ; the called party's progress using protocol-agnostic
96 ; capabilities. Like with generic CC agents, generic CC
97 ; monitors should only be used for phones.
99 ;native: Analogous to the cc_agent_policy setting. We will use
100 ; protocol-specific methods to request CC from this interface
101 ; and to monitor the interface for availability.
103 ;accept: If an interface is set to "accept," then we will accept
104 ; protocol-specific CC offers from the caller and use
105 ; a native CC monitor for the remainder of the CC transaction.
106 ; However, if the interface does not offer protocol-specific
107 ; CC, then we will fall back to using a generic CC monitor
108 ; instead. This is a good setting to use for phones for which
109 ; you do not know if they support protocol-specific CC
111 ;cc_monitor_policy=never
114 ;---------------------------------------------------------------------
116 ;---------------------------------------------------------------------
118 ; The use of CC requires Asterisk to potentially use more memory than
119 ; some administrators would like. As such, it is a good idea to limit
120 ; the number of CC requests that can be in the system at a given time.
121 ; The values shown below are the defaults.
123 ; The cc_max_agents setting limits the number of outstanding CC
124 ; requests a caller may have at any given time. Please note that due
125 ; to implementation restrictions, this setting is ignored when using
126 ; generic CC agents. Generic CC agents may only have one outstanding
131 ; The cc_max_monitors setting limits the number of outstanding CC
132 ; requests can be made to a specific interface at a given time.
136 ;---------------------------------------------------------------------
138 ;---------------------------------------------------------------------
140 ; When using a generic CC agent, the caller who requested CC will be
141 ; called back when a called party becomes available. When the caller
142 ; answers his phone, the administrator may opt to have a macro run.
143 ; What this macro does is up to the administrator. By default there
144 ; is no callback macro configured.
148 ; When using an ISDN phone and a generic CC agent, Asterisk is unable
149 ; to determine the dialstring that should be used when calling back
150 ; the original caller. Furthermore, if you desire to use any dialstring-
151 ; specific options, such as distinctive ring, you must set this
152 ; configuration option. For non-ISDN phones, it is not necessary to
153 ; set this, since Asterisk can determine the dialstring to use since
154 ; it is identical to the name of the calling device. By default, there
155 ; is no cc_agent_dialstring set.
