I don't know about relicense thing...but I did contacted FreeSwitch/Polycom.
I sent email to Steve Underwood(author of libg722_1) and Brian
West(one of FreeSwitch founder)
and they said I can use the libg722_1 in freeswitch repo.
I also left note in polycom.com - 'Contact Us'  and still waiting for answer.
