If I had, I would have more solidly initialized the opts element for varset. ........ git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@124541 65c4cc65-6c06-0410-ace0-fbb531ad65f3

" ForkCDR([options]): Causes the Call Data Record to fork an additional\n"

|
|
"be linked to end of the list of cdr records attached to the channel. The original CDR is\n"
|
|
"has a LOCKED flag set, which forces most cdr operations to skip it, except\n"
|
|
"for the functions that set the answer and end times, which ignore the LOCKED\n"
|
|
"flag. This allows all the cdr records in the channel to be 'ended' together\n"
|
|
"when the channel is closed.\n"
|
|
"The CDR() func (when setting CDR values) normally ignores the LOCKED flag also,\n"
|
|
"but has options to vary its behavior. The 'T' option (described below), can\n"
|
|
"override this behavior, but beware the risks.\n"
|
|
"\n"
|
|
"Detailed Behavior Description:\n"
|
|
"First, this app finds the last cdr record in the list, and makes\n"
|
|
"a copy of it. This new copy will be the newly forked cdr record.\n"
|
|
"Next, this new record is linked to the end of the cdr record list.\n"
|
|
"Next, The new cdr record is RESET (unless you use an option to prevent this)\n"
|
|
"This means that:\n"
|
|
" 1. All flags are unset on the cdr record\n"
|
|
" 2. the start, end, and answer times are all set to zero.\n"
|
|
" 3. the billsec and duration fields are set to zero.\n"
|
|
" 4. the start time is set to the current time.\n"
|
|
" 5. the disposition is set to NULL.\n"
|
|
"Next, unless you specified the 'v' option, all variables will be\n"
|
|
"removed from the original cdr record. Thus, the 'v' option allows\n"
|
|
"any CDR variables to be replicated to all new forked cdr records.\n"
|
|
"Without the 'v' option, the variables on the original are effectively\n"
|
|
"moved to the new forked cdr record.\n"
|
|
"Next, if the 's' option is set, the provided variable and value\n"
|
|
"are set on the original cdr record.\n"
|
|
"Next, if the 'a' option is given, and the original cdr record has an\n"
|
|
"answer time set, then the new forked cdr record will have its answer\n"
|
|
"time set to its start time. If the old answer time were carried forward,\n"
|
|
"the answer time would be earlier than the start time, giving strange\n"
|
|
"duration and billsec times.\n"
|
|
"Next, if the 'd' option was specified, the disposition is copied from\n"
|
|
"the original cdr record to the new forked cdr.\n"
|
|
"Next, if the 'D' option was specified, the destination channel field\n"
|
|
"in the new forked CDR is erased.\n"
|
|
"Next, if the 'e' option was specified, the 'end' time for the original\n"
|
|
"cdr record is set to the current time. Future hang-up or ending events\n"
|
|
"will not override this time stamp.\n"
|
|
"Next, If the 'A' option is specified, the original cdr record will have\n"
|
|
"it ANS_LOCKED flag set, which prevent future answer events\n"
|
|
"from updating the original cdr record's disposition. Normally, an\n"
|
|
"'ANSWERED' event would mark all cdr records in the chain as 'ANSWERED'.\n"
|
|
"Next, if the 'T' option is specified, the original cdr record will have\n"
|
|
"its 'DONT_TOUCH' flag set, which will force the cdr_answer, cdr_end, and\n"
|
|
"cdr_setvar functions to leave that cdr record alone.\n"
|
|
"And, last but not least, the original cdr record has its LOCKED flag\n"
|
|
"set. Almost all internal CDR functions (except for the funcs that set\n"
|
|
"the end, and answer times, and set a variable) will honor this flag\n"
|
|
"and leave a LOCKED cdr record alone.\n"
|
|
"This means that the newly created forked cdr record will affected\n"
|
|
"by events transpiring within Asterisk, with the previously noted\n"
|
|
"exceptions.\n"
|
|
" Options:\n"
|
|
" a - update the answer time on the NEW CDR just after it's been inited..\n"
|
|
" The new CDR may have been answered already, the reset that forkcdr.\n"
|
|
" does will erase the answer time. This will bring it back, but\n"
|
|
" the answer time will be a copy of the fork/start time. It will.\n"
|
|
" only do this if the initial cdr was indeed already answered..\n"
|
|
" A - Lock the original CDR against the answer time being updated.\n"
|
|
" This will allow the disposition on the original CDR to remain the same.\n"
|
|
" d - Copy the disposition forward from the old cdr, after the .\n"
|
|
" init..\n"
|
|
" D - Clear the dstchannel on the new CDR after reset..\n"
|
|
" e - end the original CDR. Do this after all the necc. data.\n"
|
|
" is copied from the original CDR to the new forked CDR..\n"
|
|
" R - do NOT reset the new cdr..\n"
|
|
" s(name=val) - Set the CDR var 'name' in the original CDR, with value.\n"
|
|
" 'val'.\n"
|
|
" T - Mark the original CDR with a DONT_TOUCH flag. setvar, answer, and end\n"
|
|
" cdr funcs will obey this flag; normally they don't honor the LOCKED\n"
|
|
" flag set on the original CDR record.\n"
|
|
" Beware-- using this flag may cause CDR's not to have their end times\n"
|
|
" updated! It is suggested that if you specify this flag, you might\n"
