Hi Marco,
Ser has IP of Asterisk server in his "trusted" table, Asterisk isn't
registered in Ser. When Ser needs to use Asterisk, it simply rewrites
the IP destination with Asterisk's IP, and routes them to him.
For example, here's one failed attempt in transferring a call PSTN ->
VoIP -> VoIP:
PSTN Asterisk Ser
phone_A phone_B

In this example, phone_A answers the PSTN originated call, and wants to
transfer the call to phone_B. A REFER message is than routed backwards
to Asterisk, and he replies with those 404 Not Found messages. Phone_B
never gets called!
Should Asterisk be registered in Ser so this can work properly? How can
that be done?
Thanks,
Ricardo.
