ipbx call recording allows you to record all or select calls passing through your PBX system. Check your jurisdiction's laws regarding call recording.

Generally, it is legal to record any conversation where all the parties to it have given their consent (one-party consent if all the parties are in a state with a corresponding law). U.S. federal law requires only one-party consent to the recording of a telephone conversation, but does not explicitly protect such a recording if it is made for criminal or tortuous purposes. Many states make similar exceptions.

Storage & Limits

Call recording is storage intensive and should be carefully planned. Standard ipbx configurations use the local database and disk for call recordings. It is advisable to use a separate disk, or storage array for more than occasional recording. One hour of call recording takes up about 5.7MB of disk space. A 500GB drive will thus be able to store in excess of 70,000 hours in GSM format.

In order for ipbx to properly handle and play back recordings that are bigger than 16MB, you will need to adjust your php.ini configuration (on standard ipbx distributions this file can be found under /etc/php.ini). The relevant limit is:

 memory_limit = 128M

Make sure to restart the ipbx tasker service and HTTP server by entering:

 [root@ipbx ~]# service ipbx restart
 [root@ipbx ~]# service httpd restart

Later versions of ipbx have a preset limit of 128MB and usually don't require any changes.

Further limits on database storage are imposed by the MySQL backend and might need be adjusted as well.

 [mysqld]
 max_allowed_packet = 128M
 query_cache_size = 128M

remember to restart the MySQL backend by typing:

 [root@ipbx ~]# service mysqld restart

Unprocessed recordings which haven't shown up in the recordings table, will still be in the /tmp/ directory of the ipbx system. A restart of the tasker will automatically cause these to be stored in the database. Do not restart your ipbx system before moving the files out of the /tmp/ directory unless they have been already stored in your recordings table.
