Zaptel installation issues


I am trying to install zaptel1.4 in a machine, where i do not have internet access to it.

when compiling (make install) i get the following error

make -C firmware hotplug-install DESTDIR= HOTPLUG_FIRMWARE=yes
make[1]: Entering directory /usr/src/zaptel-1.4/firmware' Attempting to download zaptel-fw-oct6114-064-1.05.01.tar.gz --18:55:07-- [ ... .01.tar.gz]( =>zaptel-fw-oct6114-064-1.05.01.tar.gz’

make[1]: Leaving directory `/usr/src/zaptel-1.4/firmware’
make: *** [install-firmware] Error 2

I understand, it is trying to download a file from internet, my concern is internet connectivity to the machine. Internet access to this machine is denied by default by my IT team.

how could i fix this installation issues, but i can download the same file from some other system and i can copy it.

How could do i fix this issues?

Thanks in advance
