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
