Call Sign Routing to various user call signs

[Aussie Susan]

I have several call signs registered for the D-Star network - one with just my call sign and others with 'M' and 'P' for when I'm mobile/portable.

My question is: do each of these appear as different 'users' for the purposes of call sign routing?

For example: I use my standard call sign in my home town, and then fly to another city where I use the 'P' variant. Someone wants to contact me and enters my standard call sign as the 'Your Call" (UR or whatever) - does this get routed to the last place I used my standard call sign or to the last place I used any variant of my call sign?

Thanks

Yes, a better term might be "station routing".  All eight characters are used for routing.  By definition in the specification, the eighth character is a station ID.  The protocol does not support multiple stations in the header.  Icom and Robin's DPlus have implemented versions of "callsign routing" which basically allows multicast to repeaters.  In the future, this might be implemented for individual stations.  However, the implication of multicast to users specified by users could possibly lead to multiple repeaters being tied up for a one-to-one communication.  Just something that would need to be accounted for.

Have fun!
