* acl (named_acl.c) * cdr * cel * ccss * dnsmgr * dsp * enum * extconfig (config.c) * features * http * indications * logger * manager * plc * sounds * udptl These modules are now loaded at appropriate time by the module loader. Unlike loadable modules these use AST_MODULE_LOAD_FAILURE on error so the module loader will abort startup on failure of these modules. Some of these modules are still initialized or shutdown from outside the module loader. logger.c is initialized very early and shutdown very late, manager.c is initialized by the module loader but is shutdown by the Asterisk core (too much uses it without holding references).

The values are as follows:

"accountcode", accountcode is the account name of detail records, Master.csv contains all records *
|
|
Detail records are configured on a channel basis, IAX and SIP are determined by user *
|
|
DAHDI is determined by channel in dahdi.conf

"destination context",
|

"callerid",
|
|
"channel",
|
|
"destination channel", (if applicable)
|
|
"last application", Last application run on the channel
|
|
"last app argument", argument to the last channel
|
|
"start time",
|
|
"answer time",
|
|
"end time",
|
|
duration, Duration is the whole length that the entire call lasted. ie. call rx'd to hangup
|
|
"end time" minus "start time"
|
|
billable seconds, the duration that a call was up after other end answered which will be <= to duration
|
|
"end time" minus "answer time"
|
|
"disposition", ANSWERED, NO ANSWER, BUSY
|
|
"amaflags", DOCUMENTATION, BILL, IGNORE etc, specified on a per channel basis like accountcode.
|
|
"uniqueid", unique call identifier
|

"userfield" user field set via SetCDRUserField
