I just use FS's CLI  to call zoiper from FS, it works OK

CLI cmd :  originate sofia/internal/1001 at 192.168.26.39:25060 1001

i think if i want to do send fax from FS, i need one softphone can receive
fax, zoiper can do this or not? That is a question...

> Zopier is ok, but it's far from a perfect piece of software.
> Perhaps it is not able to receive a fax when it calls out.
> Could you try to call Zoiper from FS before sending the fax to Zoiper ?
