Is it possible for freeswitch to communicate directly with an Altigen's PRI interface w/hardware or would freeswitch be able to send transfers as SIP INFO + flash as this is how Altigen support says the Altigen PBX handles transfer requests via SIP.
 
Also, does anyone have any idea where I can find documentation os the specifics of using freeswitch as an SBC?
 
Thanks.
