[SR-Users] Event when acc is written?

[Tobias]

Hi Daniel,


Thanks for your reply.


Disregarding the MySQL ID, would it be possible to get the callid of the call back from the acc module once a write has been made?


Thanks,

/Tobias

Hi Daniel,


I'd still like the acc record to be written, and then get notified about that writing was completed, including the mysql ID, callid and maybe something more, perhaps the whole record written? I'd like a notification for all writes, i.e. doesn't matter if it's acc.acc or acc.missed_calls, INVITEs or BYE, etc.

the MySQL ID is specific to MySQL (and maybe few other database engines), but not involving acc at all. So you can't get that in the config right now with acc module -- for example the acc module uses the same mechanism to write the record to syslog or send it to radius, where no ID is involved.

To some extent you may be able to do it in configuration file by replacing the acc default behaviour with sqlops. The records are written by mysql when 200ok is received (which can be caught via an onreply_route) or a final negative response is handled (which can be caught via a failure_route). There you can use acc_db_request() to write the record to database and then sqlops to retrieve the ID. Just an idea by now, but it seems to be doable ...

Cheers,
Daniel



Kind regards,

/Tobias

Hi!


I'm wondering if there is a way for the acc-module to notify/send an event to Kamailio (so I can pick it up from the config, similar to event_route) once the acc-module has performed a write?


As an example I'm using acc and db-mysql to store acc data in MySQL, but instead of having a service polling the MySQL for new acc's written I'd like to make Kamailio send an event once an acc-row has been written. I realize this could most likely be done by using MySQL triggers "ON INSERT", but I'm wondering if there is another (reliable) way to do this directly from within Kamailio?


I haven't tested it, but I would guess that if I tried to use for example event_route[dialog:end] there could be times where the event would hit Kamailio before the acc-module have written to missed_calls?


Do you still want the acc record to be written in the database or catch the event before storing and directing it somewhere else?

Cheers,
Daniel
