[SR-Users] Search all dialogs - Kamailiio 3.0.3

[Charles Chance]

Hi Daniel,

 

Thanks for your reply. We are going to upgrade to 3.2 so that we can make
use of the variables for now and start playing around with the devel version
ready for the next release :-)

 

Cheers,

 

Charles

Hi all,

 

I was wondering if anyone could offer any advice please.

 

We are using the dialog module and need to be able to find out whether
another dialog exists within a particular profile and having a specific
value, so that we can send the new call to the same gateway. As far as I am
aware, the only way to see other dialogs from the request route is to query
the database (having set db mode to realtime). This is ok, but the
profile/value is not stored in the database table. Is there a way of
fetching the information that I am missing, or should we just add some
customisation to the module so that it also writes this information to db?

in the last version you can attach variables to dialog and they are stored
in database -- but that requires you to upgrade. Also, devel version saves
the profiles in database, in a json format.

What you can do with 3.0.x:
- use sqlops to write to db table the info you need -- you would have to
update db based on call events, such as initial invite: insert record to db;
200ok to initial invite, confirm the dialog in the record; bye: delete the
db record; you need to delete also for the case of negative reply to invite.
You can use rtimer to delete old records (those that don't get bye). This is
pretty much what dialog module does, but hides it in the c code -- all
doable in the config
- use htable module to store the details in memory instead of a db table

In summary: upgrading to 3.2.x makes your life much easier. Next major
release comes with a better dialog storage, you may want to play with it as
well.

Cheers,
Daniel
