Overview
This is a work-in-progress charm to deploy and operate Asterisk as a
virtualized network service (VNF), currently focusing on SIP functionality.
This has been successfully tested on LXD and Amazon EC2.
Once the asterisk charm has been deployed, configured, and a user added, you
can test it out by using a SIP phone, configured with the new users credentials,
and call extension 100. If successful, you should here a brief message.
Usage
juju deploy cs:~aisrael/asterisk
juju expose asterisk
If you are deploying to Amazon EC2 or other cloud that uses NAT, you'll need
to enable this functionality:
juju set asterisk sip-nat='yes'
By default, no users have been added. To do that, run the add-user action,
specifying the username and password.
juju run-action asterisk/0 add-user username=demo password=demo
Scale out Usage
None yet.
Known Limitations and Issues
The charm is pretty limited at the moment.
- The
pjsipmodule is disabled, due to a bug in the Ubuntu 16.04 asterisk package. The package will need to be fixed in order for that module to be enabled. - Does not auto-detect NAT
- Configuration options are limited.
- dialpans are not configurable yet.
Configuration
- sip-nat: 'yes', 'no', 'force_rport', or 'comedia'. Please note that only 'yes' has been tested.
- sip-port: The SIP port to listen on.
