" Options:\n"
" A(x) - Play an announcement to the called party, using 'x' as the file.\n"
" C - Reset the CDR for this call.\n"
" d - Allow the calling user to dial a 1 digit extension while waiting for\n"
" a call to be answered. Exit to that extension if it exists in the\n"
" current context, or the context defined in the EXITCONTEXT variable,\n"
" if it exists.\n"
" D([called][:calling]) - Send the specified DTMF strings *after* the called\n"
" party has answered, but before the call gets bridged. The 'called'\n"
" DTMF string is sent to the called party, and the 'calling' DTMF\n"
" string is sent to the calling party. Both parameters can be used\n"
" alone.\n"
" f - Force the callerid of the *calling* channel to be set as the\n"
" extension associated with the channel using a dialplan 'hint'.\n"
" For example, some PSTNs do not allow CallerID to be set to anything\n"
" other than the number assigned to the caller.\n"
" g - Proceed with dialplan execution at the current extension if the\n"
" destination channel hangs up.\n"
" G(context^exten^pri) - If the call is answered, transfer both parties to\n"
" the specified priority. Optionally, an extension, or extension and\n"
" context may be specified. Otherwise, the current extension is used.\n"
" h - Allow the called party to hang up by sending the '*' DTMF digit.\n"
" H - Allow the calling party to hang up by hitting the '*' DTMF digit.\n"
" j - Jump to priority n+101 if all of the requested channels were busy.\n"
" L(x[:y][:z]) - Limit the call to 'x' ms. Play a warning when 'y' ms are\n"
" left. Repeat the warning every 'z' ms. The following special\n"
" variables can be used with this option:\n"
" * LIMIT_PLAYAUDIO_CALLER yes|no (default yes)\n"
" Play sounds to the caller.\n"
" * LIMIT_PLAYAUDIO_CALLEE yes|no\n"
" Play sounds to the callee.\n"
" * LIMIT_TIMEOUT_FILE File to play when time is up.\n"
" * LIMIT_CONNECT_FILE File to play when call begins.\n"
" * LIMIT_WARNING_FILE File to play as warning if 'y' is defined.\n"
" The default is to say the time remaining.\n"
" m([class]) - Provide hold music to the calling party until a requested\n"
" channel answers. A specific MusicOnHold class can be\n"
" specified.\n"
" M(x[^arg]) - Execute the Macro for the *called* channel before connecting\n"
" to the calling channel. Arguments can be specified to the Macro\n"
" using '^' as a delimeter. The Macro can set the variable\n"
" MACRO_RESULT to specify the following actions after the Macro is\n"
" finished executing.\n"
" * ABORT Hangup both legs of the call.\n"
" * CONGESTION Behave as if line congestion was encountered.\n"
" * BUSY Behave as if a busy signal was encountered. This will also\n"
" have the application jump to priority n+101 if the\n"
" 'j' option is set.\n"
" * CONTINUE Hangup the called party and allow the calling party\n"
" to continue dialplan execution at the next priority.\n"
" * GOTO:<context>^<exten>^<priority> - Transfer the call to the\n"
" specified priority. Optionally, an extension, or\n"
" extension and priority can be specified.\n"
" n - This option is a modifier for the screen/privacy mode. It specifies\n"
" that no introductions are to be saved in the priv-callerintros\n"
" directory.\n"
" N - This option is a modifier for the screen/privacy mode. It specifies\n"
" that if callerID is present, do not screen the call.\n"
" o - Specify that the CallerID that was present on the *calling* channel\n"
" be set as the CallerID on the *called* channel. This was the\n"
" behavior of Asterisk 1.0 and earlier.\n"
" p - This option enables screening mode. This is basically Privacy mode\n"
" without memory.\n"
" P([x]) - Enable privacy mode. Use 'x' as the family/key in the database if\n"
" it is provided. The current extension is used if a database\n"
" family/key is not specified.\n"
" r - Indicate ringing to the calling party. Pass no audio to the calling\n"
" party until the called channel has answered.\n"
" S(x) - Hang up the call after 'x' seconds *after* the called party has\n"
" answered the call.\n"
" t - Allow the called party to transfer the calling party by sending the\n"
" DTMF sequence defined in features.conf.\n"
" T - Allow the calling party to transfer the called party by sending the\n"
" DTMF sequence defined in features.conf.\n"
" w - Allow the called party to enable recording of the call by sending\n"
" the DTMF sequence defined for one-touch recording in features.conf.\n"
" W - Allow the calling party to enable recording of the call by sending\n"
" the DTMF sequence defined for one-touch recording in features.conf.\n";
