When I receive a call, they say "The number you dialed is disconnected" Why?

Question

Asterisk

There is FreeBPX 13 (PBX Firmware:10.13.66-9 PBX Service Pack:1.0.0.0). For nat.

Trunk configured :
username=73838
type=friend
secret=
qualify=yes
port=5060
nat=yes
insecure=invite
host=172.26.160.25
fromuser=73838
fromdomain=172.26.160.25
context=from-trunk

Trunk registered:
TR-73838/73 172.26 .160.25 No No 5060 OK (8 ms)

But when I receive a call to this number, they tell me "The number you dialed is disconnected"

Here is the log:
