  • Page 4: Preparation

    Preparation This chapter contains all information that is necessary to connect an OpenStage phone to an Asterisk based communication system. This includes the power supply options (PoE or external supply) for each OpenStage model and its possible sidecar combinations. To enable a secure environment, 802.1x support for OpenStage is specified.
  • Page 5 Energy saving mode To reduce the energy consumption to a minimum, OpenStage phones offer an energy saving mode. The display backlight (phone and Key Module, if attached) is switched off after a configurable timeout. With OpenStage 40, the main display and key module backlight will be switched off after 90 seconds of inactivity (firmware version V2R0 onwards).

If a Firewall or NAT get in the Way In case the phones and the provisioning service reside in different networks or subnets that are separated by a firewall and/or NAT, it may be impossible for the provisioning service to contact the phones.

  • Page 10: Call Completion (Ccbs/Ccnr)

    An implementation according to the IETF BLISS draft is planned, but currently not available. The OpenStage call completion implementation is purely stimulus based and can be found CTI for OpenStage - UACSTA There are several use cases where remote control of a VoIP phone is required. Among these are server based features like ‘Call Forwarding’...
  • Page 11: Changing The Caller Information - Pai Header

    OpenStage does not generate CSTA Events. With these services a SIP server can easily control basic OpenStage functions. For futher information please have a look at: http://wiki.siemens- Changing the Caller Information – PAI Header SIP is a great protocol for call processing. However, in some use cases, additional and up-to- date information about a caller might prove to be very useful.
  • Page 12: Multi Address Appearance (Maa)

    Multi Address Appearance (MAA) A telephone is normally associated with a directory number, or, generally, with a SIP AoR. This number is used for placing calls to the associated telephone and for displaying the telephone's (user's) identity when placing calls to another party. The number is also used when more than one call appearance is supported due to additional features like call waiting.
  • Page 13: Automatic Call Pickup - Using Alert Info Header

    Example: OpenStage operates in MAA mode. Further information can be found at: Automatic Call Answering Using Alert-Info Header Besides using uaCSTA, the phone can be set to automatically answer a call by adding an alert info header to the call. Thus, the SIP server is enabled to control whether a call is to be answered immediately and without user interaction.
  • Page 14: Logging And Tracing

    Logging and Tracing OpenStage phones are perfect. But if something should go wrong anyhow, the customer service needs tools to focus on the problem. Service effort is needed, but should be minimized. Therefore, OpenStage phones provide plenty of tools and options to find the cause of a problem quickly, even if it is not located at the phone.
  • Page 15: Local And Remote Tracing

    Local and Remote Tracing The phone is able to write internal trace files, and to send the trace data to a remote syslog server. The tracing can be configured in a differentiated way by setting discrete trace levels for each service. Please note that it is not recommended to enable all traces to the deepest level.
