Talker Alias is a new great possibility added to ETSI DMR specifications in 2016. Its behavior is fully same as Free-Text in D-STAR: a radio transmits text data (as well as it can transmit GPS location) during voice call. We have added two important things to BrandMeister DMR Server:

  • Pass-thru of embedded signaling data (TalkerAlias and GPS) over BrandMeister (if protocol supports this)
  • Generation of Talker Alias in many applications such as Simple Application Protocol, AutoPatch, D-STAR and Fusion gateways


Specification is available here - http://www.etsi.org/deliver/etsi_ts/102300_102399/10236102/02.03.01_60/ts_10236102v020301p.pdf page 52

FAQ

  • Can you turn it of on a per user basis
    • No this is not possible (due the nature of group calls)
  • I have issues with audio on my radio
    • Please send PD0ZRY a email pd0zry@pd0zry.nl with the following information
      • Does it happen every call or only some of them
        • if some of them is it specific to a user or not?
      • Radio type
      • Radio firmware (don't say most recent)
      • Repeater or hotspot it has been received on (only the ID is needed)
      • Possibly even a video / audio of the problem happening
