AX.25 digipeating contains the callsign of the digipeating station as
well.

When a digipeater repeats a frame it flips a bit to say that it has done
it so I assume you're not talking about vanilla AX.25 digipeating here.
The only system in common use that doesn't id the transmitter's callsign
seems to be NET/ROM.
