This feature enhances the existing OpenStage phone’s DLS interface by providing a means for the OpenStage SIP Phone to make use of a DLS Server which is deployed behind a Firewall/NAT. Supporting DLS usage in NATed environments like hosted HiPath 8000 environment, a DLS Contact Me Proxy (DCMP) was introduced with optiPoint SIP phones. This feature is now also available for OpenStage SIP Phones.

A detailed description can be found in the updated OpenWPI documentation for V2 R0

Short Overview

What is the Problem?

Solution Overview

Device Requirements

  • Configuration of DCMP URL and poll interval via DLS. Note: the Contact-Me is still mandatory and to be supported in any case (and always active, independent of the device's DCMP configuration). Their current value need not to be stored persistently on the device: every restart of the device leads to a startup-request to DLS, where the current valid settings of these items are obtained.
  • Execute poll requests at the required interval (in addition to listening on contact-me) and check HTTP return status code. The status code 202 ACCEPTED indicates that pending DLS jobs are available. The device should open a DLS session using the ReasonForContact = solicited.

Note: Any contact to DLS (e.g. due to device start-up, local-changes, inventory-changes, etc.) should restart the timer for the DCMP poll interval
