is there any way to modify the Q931 Call Progress Indicator? I need to setup Q931_PROG_CALLED_NOT_ISDN, “Called equipment is non-ISDN.” due to some other-end-HW-PBX obstacles. Everything is in libPRI source (q931.c) but is there any way how to modify this from Asterisk?
I’m using TE205P.
TNX in advance
