According to TS 24.229, The AS could send request to SCSCF, too.
But some rules shall be obeied.
For example did you add P-Asserted-Identity header to your request?

Hello Mojtaba,
Thanks for your reply. You are completely correct, my current
configuration work fine when request initiated from UEs, but I want to
handle SIP requests that initiated by application server.
When UE sends request to S-CSCF, kamailio fetch iFC from HSS and check if
the request match with iFC or not, if it matched kamailio forward the
request to the application server.
But when application server send request to S-CSCF, isc_from_as('orig')
return false and I couldn't forward request to the target UE.
Regards,
Ali

Hello Ali,
The SCSCF has IFC service for decision what it should do with incoming
SIP message. During check all rules in IFC, If it match with one or some
rules, actually it marked with that rules. Then the real meaning of marking
is the SIP message is matched with one or some rules in IFC.
With Best Regards.

Hi all,
I read some portion of imc_isc_mod.c, specially isc_from_as function. In
that function there is some function call that searching for some marks in
the SIP message. Also I read section 5.7.3 from TS 24.229 but I didn't find
the marking mechanism that used in isc_from_as function.
Would you please point me to the technical specification that
implemented in IMS_ISC module?
Regards,
Ali
