Receive Voice Call screen

[onbypass]

I will be receiving my G5 next week. I am coming from a traditional Uniden Home Patrol 2 scanner and all its terminology.
I notice in videos, that when a "voice call" is received, I see there is a "To" and a "From". The "To" appears to be a TGID of a P25 system that you are monitoring.
The "From" seems to just have numbers. I can't figure out what those numbers are and can they or should they be changed to an alias?
Just for reference, I will be mostly monitoring the "fire" based TGIDs, in the "Grand Junction" area, as part of the "Colorado DTRS" system!

THANKS, in advance, for your help.

The TO is usually the TGID which typically you will have an alias for, provided this is a group call and not a private call. The FROM is the radio/unit ID number assigned to the radio making the call, you can assign an alias to this if known in the PPS in C1 or E2 (depending which you use) Individual Call List column, if you know the alias, but you do not need to assign one.

Most of the time you would not assign the alias unless it is a smaller department or you want to identify a particular person, as you are limited to 999 entries. These also must be added for all TGs the alias might be seen on, as it is TG specific not system wide.

THANK YOU!!! That explains it perfectly. That's something I don't usually see when using a regular scanner!!
My personal programming thought is to have zones for systems in different areas that I might travel to, and knob positions for my personal TGID groups within those systems.
Thanks again for the quick reply.
