Hi,

here is my env config:

PSTN (ISDN trunk_ -> CM (v. 6.2.3) -> (SIP tie trunk) Asterisk

All calls works fine except case when CM receives from PSTN frame with denial cause code (e.g. ISDN cause 1 "Unassigned number") and progress flag.
ISDN frame looks like:

3 12:05:41.737 60 00003e0f ==> DISC crv 1_522d unassgd num !
D-channel port number: 00003e0f
Protocol Discriminator: 08 call control
Call Reference Value: 02 d2 2d Destination 522d
Q.931 Message Type: 45 Disconnect
=> CAUSE rmt pub netwk: 1. Unassigned number / SIT-intercept
=> PROGRESS IND 82 88 local pub netwk, in-band info/pattern avail

In that scenario CM does not send to Asterisk "404 Not Found" and call finishes when PSTN sends timeout.
Is there any way to force CM to send SIP 404 ? Thanks.
