I would dare say that it would probably be best to not even explicitly send an REL at that point, just set the SOFTHANGUP flag on the ast_channel so that Asterisk will initiate the hangup at that point. That is how it is done in libpri in a similar scenario, if you look at PRI_EVENT_PROGRESS handling code in chan_dahdi.c.
