-= Info about application 'Dial' =- [Synopsis] Place a call and connect to the current channel [Description] Dial(Technology/resource[&Tech2/resource2...][|timeout][|options][|URL]): This application will place calls to one or more specified channels. As soon as one of the requested channels answers, the originating channel will be answered, if it has not already been answered. These two channels will then be active in a bridged call. All other channels that were requested will then be hung up. Unless there is a timeout specified, the Dial application will wait indefinitely until one of the called channels answers, the user hangs up, or if all of the called channels are busy or unavailable. Dialplan executing will continue if no requested channels can be called, or if the timeout expires. This application sets the following channel variables upon completion: DIALEDTIME - This is the time from dialing a channel until when it is disconnected. ANSWEREDTIME - This is the amount of time for actual call. DIALSTATUS - This is the status of the call: CHANUNAVAIL | CONGESTION | NOANSWER | BUSY | ANSWER | CANCEL DONTCALL | TORTURE | INVALIDARGS For the Privacy and Screening Modes, the DIALSTATUS variable will be set to DONTCALL if the called party chooses to send the calling party to the 'Go Away' script. The DIALSTATUS variable will be set to TORTURE if the called party wants to send the caller to the 'torture' script. This application will report normal termination if the originating channel hangs up, or if the call is bridged and either of the parties in the bridge ends the call. The optional URL will be sent to the called party if the channel supports it. If the OUTBOUND_GROUP variable is set, all peer channels created by this application will be put into that group (as in Set(GROUP()=...). If the OUTBOUND_GROUP_ONCE variable is set, all peer channels created by this application will be put into that group (as in Set(GROUP()=...). Unlike OUTBOUND_GROUP, however, the variable will be unset after use. Options: A(x) - Play an announcement to the called party, using 'x' as the file. C - Reset the CDR for this call. d - Allow the calling user to dial a 1 digit extension while waiting for a call to be answered. Exit to that extension if it exists in the current context, or the context defined in the EXITCONTEXT variable, if it exists. D([called][:calling]) - Send the specified DTMF strings *after* the called party has answered, but before the call gets bridged. The 'called' DTMF string is sent to the called party, and the 'calling' DTMF string is sent to the calling party. Both parameters can be used alone. f - Force the callerid of the *calling* channel to be set as the extension associated with the channel using a dialplan 'hint'. For example, some PSTNs do not allow CallerID to be set to anything other than the number assigned to the caller. g - Proceed with dialplan execution at the current extension if the destination channel hangs up. G(context^exten^pri) - If the call is answered, transfer the calling party to the specified priority and the called party to the specified priority+1. Optionally, an extension, or extension and context may be specified. Otherwise, the current extension is used. You cannot use any additional action post answer options in conjunction with this option. h - Allow the called party to hang up by sending the '*' DTMF digit. H - Allow the calling party to hang up by hitting the '*' DTMF digit. i - Asterisk will ignore any forwarding requests it may receive on this dial attempt. j - Jump to priority n+101 if the called party was busy. Jump to priority n+201 if all of the requested channels were busy. k - Allow the called party to enable parking of the call by sending the DTMF sequence defined for call parking in features.conf. K - Allow the calling party to enable parking of the call by sending the DTMF sequence defined for call parking in features.conf. L(x[:y][:z]) - Limit the call to 'x' ms. Play a warning when 'y' ms are left. Repeat the warning every 'z' ms. The following special variables can be used with this option: * LIMIT_PLAYAUDIO_CALLER yes|no (default yes) Play sounds to the caller. * LIMIT_PLAYAUDIO_CALLEE yes|no Play sounds to the callee. * LIMIT_TIMEOUT_FILE File to play when time is up. * LIMIT_CONNECT_FILE File to play when call begins. * LIMIT_WARNING_FILE File to play as warning if 'y' is defined. The default is to say the time remaining. m([class]) - Provide hold music to the calling party until a requested channel answers. A specific MusicOnHold class can be specified. M(x[^arg]) - Execute the Macro for the *called* channel before connecting to the calling channel. Arguments can be specified to the Macro using '^' as a delimeter. The Macro can set the variable MACRO_RESULT to specify the following actions after the Macro is finished executing. * ABORT Hangup both legs of the call. * CONGESTION Behave as if line congestion was encountered. * BUSY Behave as if a busy signal was encountered. This will also have the application jump to priority n+101 if the 'j' option is set. * CONTINUE Hangup the called party and allow the calling party to continue dialplan execution at the next priority. * GOTO:^^ - Transfer the call to the specified priority. Optionally, an extension, or extension and priority can be specified. You cannot use any additional action post answer options in conjunction with this option. Also, pbx services are not run on the peer (called) channel, so you will not be able to set timeouts via the TIMEOUT() function in this macro. n - This option is a modifier for the screen/privacy mode. It specifies that no introductions are to be saved in the priv-callerintros directory. N - This option is a modifier for the screen/privacy mode. It specifies that if callerID is present, do not screen the call. o - Specify that the CallerID that was present on the *calling* channel be set as the CallerID on the *called* channel. This was the behavior of Asterisk 1.0 and earlier. O([x]) - "Operator Services" mode (Zaptel channel to Zaptel channel only, if specified on non-Zaptel interface, it will be ignored). When the destination answers (presumably an operator services station), the originator no longer has control of their line. They may hang up, but the switch will not release their line until the destination party hangs up (the operator). Specified without an arg, or with 1 as an arg, the originator hanging up will cause the phone to ring back immediately. With a 2 specified, when the "operator" flashes the trunk, it will ring their phone back. p - This option enables screening mode. This is basically Privacy mode without memory. P([x]) - Enable privacy mode. Use 'x' as the family/key in the database if it is provided. The current extension is used if a database family/key is not specified. r - Indicate ringing to the calling party. Pass no audio to the calling party until the called channel has answered. R - indicate ringing to the calling party when the called party indicates ringing, pass no audio until answered. S(x) - Hang up the call after 'x' seconds *after* the called party has answered the call. c - callback initiation, ring once and hangup. t - Allow the called party to transfer the calling party by sending the DTMF sequence defined in features.conf. T - Allow the calling party to transfer the called party by sending the DTMF sequence defined in features.conf. w - Allow the called party to enable recording of the call by sending the DTMF sequence defined for one-touch recording in features.conf. W - Allow the calling party to enable recording of the call by sending the DTMF sequence defined for one-touch recording in features.conf.
