D8XX_BLF-XML_FR-1

On D8xx IP phones, any PFK (programmable function key - physical or virtual) can be assigned to a function, which allows monitoring state changes of the configured SIP extension on another IP phone. This function shall be called "BLF-XML". The following state changes shall be visualized:

  • monitored SIP extension is in idle mode => idle
  • monitored SIP extension seizes a line => busy
  • monitored SIP extension receives an incoming call => ringing
  • monitored SIP extension places an outgoing call => busy
  • monitored SIP extension dials or accepts an incoming call => busy

Must Have

This means, that the D8xx phone acts as a User Agent Client (UAC) and the IP phone of the monitored extension acts as User Agent Server (UAS).

D8XX_BLF-XML_FR-2

On Snom IP phones acting as UAS, any SIP extension having an active subscription of its state changes, shall sent a notification SIP message (NOTIFY) to the UAC, at least when one of the following state changes occur:

  • from any state => idle
  • from any state => trying
  • from any state => early
  • from any state => busy
