Error 2

I got following message and stopped there

make[1]: Entering directory /root/zaptel-1.4.12/firmware' Attempting to download zaptel-fw-oct6114-064-1.05.01.tar.gz --21:57:18-- [downloads.digium.com/pub/telepho ... .01.tar.gz](http://downloads.digium.com/pub/telephony/firmware/releases/zaptel-fw-oct6114-064-1.05.01.tar.gz) Resolving downloads.digium.com... failed: Temporary failure in name resolution. make[1]: *** [zaptel-fw-oct6114-064-1.05.01.tar.gz] Error 1 make[1]: Leaving directory/root/zaptel-1.4.12/firmware’
make: *** [install-firmware] Error 2

I am using behind proxy I think so
I downloaded zaptel-fw-oct6114-064-1.05.01.tar.gz and got .bin file
How can I continue my installation?

Best Regards
Please

Now I got install asterisk
but I think not work properly because of I can`t see any module and some command

test-CentOSCLI> dial
No such command ‘dial’ (type ‘help dial’ for other possible commands)
test-CentOS
CLI>

test-CentOSCLI> module show
Module Description Use Count
0 modules loaded
test-CentOS
