Is there support for RFC3578 in FreeSWITCH? If not, is there any plans
to implement it?

As far as I understand from quick browsing through this RFC, it is
about mapping of ISUP overlap signalling to SIP protocol. In short,
remote device (softswitch for example) sends short (incomplete) number
in INVITE message to freeswitch, which responds with '484 address
incomplete', then softswitch send another INVITE with more digits.
Freeswitch then can send another 484, and after some time (enough
digits collected), proceed with usual call establishment.
