Using OpenStage@Asterisk
This chapter contains some tips and tricks for operating OpenStage phones with Asterisk. It
is not intended to be exhaustive, but provides some major topics and solutions from
different successful customer projects.
Busy Lamp Function (BLF)
The “Busy Lamp Field” feature (available for OpenStage 15/40/60/80) allows users to monitor
the dialog state of another phone via the LED associated to an FPK. Please note that,
sometimes, the term 'Direct Station Selection' is used for the same functionality.
Depending on which function is configured for the FPK, the user can also pick up a call for
another user, which is of much use in working teams. The feature is described in detail here:

XML Applications
OpenStage 60/80 phones feature a graphical user interface and an XML application platform,
which allows for developing custom applications based on HTTP/HTTPS. The phone acts as a
front-end for a server-side program. The interaction can be initiated by the phone or by the
server-side program. Besides displaying, modifying, and submitting data, XML applications
have the capability of starting calls on the phone. Possible uses for OpenStage XML
Applications might be
• Integration with groupware (e.g. Microsoft Exchange Server) or Unified Messaging
systems (e.g. Siemens Enterprise Communications OpenScape)
• phonebooks with access to address databases
• call recording
• presence applications
• collecting information provided by web services (e.g. news, weather, traffic, stocks)
• attendance clock

Send URL / Remote Server Control
The FPKs and FFKs (firmware V2R1) can be utilized for communication with a server-side
program.
To enable feedback from the server, the LED associated with the key can be controlled
remotely. This can be done via SIP notify messages, or, with firmware version V2R2 onwards,
via a combination of HTTP push requests and XML documents. For detailed information,
please see the
