> If res_fax falls back to audio after timing out on T.38 upgrade, and chan_sip continues retrying the re-INVITE, and the remote end responds to one of the retransmissions (after res_fax times out) with a 200 OK, a T.38 frame will be delivered to the res_fax_spandsp driver without the t38 subsystem being initialized.
> This results in a segfault.
