Chan_dongle

Guys, I have FreePBX Stable-6.12.65, Release Date-2014, FreePBX 12, Linux 6.5 and Asterisk 11. Is Chan_dongle installed by default or should I install it to be able to connect some GSM USB dongles? If there is the need to instalation is there any step by step procedure available? kind regards
