This patch adds support for mediasec SIP headers and SDP attributes. These are defined in RFC 3329, 3GPP TS 24.229 and draft-dawes-sipcore-mediasec-parameter. The new features are implemented so that a backbone for RFC 3329 is present to streamline future work on RFC 3329. With this patch, Asterisk can communicate with Deutsche Telekom trunks which require these fields. ASTERISK-30032 Change-Id: Ia7f5b5ba42db18074fdd5428c4e1838728586be2
Asterisk Database Manager
Asterisk includes optional database integration for a variety of features. The purpose of this effort is to assist in managing the database schema for Asterisk database integration.
This is implemented as a set of repositories that contain database schema migrations, using Alembic. The existing repositories include:
cdr
- Table used for Asterisk to store CDR recordsconfig
- Tables used for Asterisk realtime configurationqueue_log
- Table used for Asterisk to store Queue Log recordsvoicemail
- Tables used forODBC_STORAGE
of voicemail messages
Alembic uses SQLAlchemy, which has support for many databases.
IMPORTANT NOTE: This is brand new and the initial migrations are still subject to change. Only use this for testing purposes for now.
Example Usage
First, create an ini file that contains database connection details. For help with connection string details, see the SQLAlchemy docs.
$ cp config.ini.sample config.ini
... edit config.ini and change sqlalchemy.url ...
Next, bring the database up to date with the current schema.
$ alembic -c config.ini upgrade head
In the future, as additional database migrations are added, you can run alembic again to migrate the existing tables to the latest schema.
$ alembic -c config.ini upgrade head
The migrations support both upgrading and downgrading. You could go all the way back to where you started with no tables by downgrading back to the base revision.
$ alembic -c config.ini downgrade base
base
and head
are special revisions. You can refer to specific revisions
to upgrade or downgrade to, as well.
$ alembic -c config.ini upgrade 4da0c5f79a9c
Offline Mode
If you would like to just generate the SQL statements that would have been executed, you can use alembic's offline mode.
$ alembic -c config.ini upgrade head --sql
Adding Database Migrations
The best way to learn about how to add additional database migrations is to refer to the Alembic documentation.
