[asterisk-users] Asterisk 13. Writing call quality parameters to CDR. How?

Hello.

Voice quality when calling - this is one of the most important in the PBX.
You need to record the quality parameters for each call to improve.

Because the overall quality of a call can only be determined upon 
completion, I did it in the HangUp handler and wrote in custom fields of 
CDR.
This worked well in asterisk 11.

In asterisk 13 I did not find a handler after the call, but before 
finalizing the CDR.
I tried to call the AGI and there to update the CDR record by unique 
identifiers. But faced with the fact that there are no needed record in 
the table yet.
To write the data into a separate table and join them may be an option. 
But do not want to resort to such a decision

How do you solve this problem?

Dmitriy Serov.

[asterisk-users] Asterisk 13. Writing call quality parameters to CDR. How?

because of problems you are facing i decided to go way with second table

CREATE TABLE `cdr_extended` (
   `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
   `uniqueid` varchar(32) NOT NULL DEFAULT '',
  `callid` varchar(256) NOT NULL DEFAULT '' COMMENT 'sip
call-id',
   `hangupcause` varchar(10) CHARACTER SET utf8 COLLATE utf8_czech_ci 
NOT NULL COMMENT 'info about hangup',
   `peerip` varchar(15) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL,
   `recvip` varchar(15) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL,
   `from_u` varchar(30) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL,
   `uri` varchar(30) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL,
   `useragent` varchar(30) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT 
NULL,
   `codec1` varchar(10) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL,
   `codec2` varchar(10) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL,
   `llp` varchar(10) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL 
COMMENT 'lost packets by local end',
   `rlp` varchar(10) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL 
COMMENT 'lost packets by remote end ',
   `ljitt` varchar(10) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL 
COMMENT 'the same for jitter ',
   `rjitt` varchar(10) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL 
COMMENT 'the same for jitter ',
   PRIMARY KEY (`id`),
   KEY `uniqueid` (`uniqueid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

in hangup handler or h exten i will use func_odbc
like
insert into cdr_extended (uniqueid,hangupcause,peerip,...) values 
('${UNIQUEID}',...);

Interesting approach.

But how to tell from a call going directly (directmedia) and a call with
asterisk in between??

In the last case, two bridged channels, how to collect the parameters from each
"leg" in the "h" extension?

Cheers
