Hi.
Can you please advise if existing ims implementation supports integration
with ims AS (Application Server), in particular for the third party
registration:
- upon UE registration is completed, S-CSCF constructs Register message
(which keeps all details of subscriber register message) and submits it to
AS server as regular SIP-message (TS 24.229 5.4.1.7 Notification of
Application Servers about registration status). S-CSCF obtains AS address
from SAA (Server Assignment Answer) diameter message, received from HSS
upon successful registration.

Hi Oleg,
This is supported by Kamailio IMS and we use it rather frequently.
However, one point is your description is not properly right:
" constructs Register message (which keeps all details of subscriber
register message) "
If you need to have all the details of the subscriber register message
(e.g. REGISTER sent by the UE), you will not find them by default in the
3rd Party registration generated by Kamailio, as it is creating a new
REGISTER (e.g. it has a new Call-ID, Contact pointing to the IMS rather
than to the UE, ...). However, you can instruct the HSS to include the
original REGISTER message as a message body or you can do a "SUBSCRIBE"
(check PUA_reginfo and related modules) for the user status in order to get
more details of the subscriber.
Thanks,
Carsten
