Upgrade W52H and W56H firmware over the air

[AMount]

Hello,

The W52H and W56H can both be connected to the same base at the same time.

When configured as documented, both handsets try downloading the same exact file when I do it this way:

Code:

################################################################################​#######
##                                  Handset_upgrade                                  ##
################################################################################​#######

#OTA upgrade of handset is not possible unless all three of these conditions are met:
#(1) Handset with firmware 26.40.0.15 or later
#(2) Base station with firmware 25.40.0.15 or later
#(3) Handset with hardware 26.0.0.6 or later
over_the_air.url = {$firmwareHandsetURL}
over_the_air.base_trigger = 0
over_the_air.handset_tip = 1

How do I make it so the W52H can download handset-26.73.0.30.rom, and the W56H can download handset-61.80.0.15.rom?
