hi there
i follow the wiki on centos 7 for google voice .
hhttp://wiki.freepbx.org/display/FOP/Installing+FreePBX+13+on+CentOS+7
but when i try to go to googlevoice section i have 
This module requires Asterisk chan_motif & res_xmpp to be installed and loaded
i already did check during the compilation that its already marked the modules :
xampp & motif
i mean the modules already marked by default and i followed the same wiki
http://wiki.freepbx.org/display/FOP/Installing+FreePBX+13+on+CentOS+7
everything is fine except googlevoice module with error above
how can i solve it ?
