"  Dial(Technology/resource[&Tech2/resource2...][|timeout][|options][|URL]):\n"
"This application will place calls to one or more specified channels. As soon\n"
"as one of the requested channels answers, the originating channel will be\n"
"answered, if it has not already been answered. These two channels will then\n"
"be active in a bridged call. All other channels that were requested will then\n"
"be hung up.\n"
"  Unless there is a timeout specified, the Dial application will wait\n"
"indefinitely until one of the called channels answers, the user hangs up, or\n"
"if all of the called channels are busy or unavailable. Dialplan executing will\n"
"continue if no requested channels can be called, or if the timeout expires.\n\n"
"  This application sets the following channel variables upon completion:\n"
"    DIALEDTIME   - This is the time from dialing a channel until when it\n"
"                   is disconnected.\n" 
"    ANSWEREDTIME - This is the amount of time for actual call.\n"
"    DIALSTATUS   - This is the status of the call:\n"
"                   CHANUNAVAIL | CONGESTION | NOANSWER | BUSY | ANSWER | CANCEL\n" 
"                   DONTCALL | TORTURE | INVALIDARGS\n"
"  For the Privacy and Screening Modes, the DIALSTATUS variable will be set to\n"
"DONTCALL if the called party chooses to send the calling party to the 'Go Away'\n"
"script. The DIALSTATUS variable will be set to TORTURE if the called party\n"
"wants to send the caller to the 'torture' script.\n"
"  This application will report normal termination if the originating channel\n"
"hangs up, or if the call is bridged and either of the parties in the bridge\n"
"ends the call.\n"
"  The optional URL will be sent to the called party if the channel supports it.\n"
"  If the OUTBOUND_GROUP variable is set, all peer channels created by this\n"
"application will be put into that group (as in Set(GROUP()=...).\n"
"  If the OUTBOUND_GROUP_ONCE variable is set, all peer channels created by this\n"
"application will be put into that group (as in Set(GROUP()=...). Unlike OUTBOUND_GROUP,\n"
"however, the variable will be unset after use.\n\n"
"  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 the calling party to\n"
"           the specified priority and the called party to the specified priority+1.\n"
"           Optionally, an extension, or extension and context may be specified. \n"
"           Otherwise, the current extension is used. You cannot use any additional\n"
"           action post answer options in conjunction with this option.\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"

"                                      Play sounds to the caller.\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"

"           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"

"                          extension and priority can be specified.\n"
"           You cannot use any additional action post answer options in conjunction\n"
"           with this option.\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"
