Hello, Maybe this link be useful to understanding the concept of Asterisk working as Telephone Application Servers(TAS) in IMS core network. https://www.youtube.com/watch?v=3nVRpzkUbIg With Regards.

Hello, personally I do not have any time these days to search or look at documents/videos/etc... to see what TAS are supposed to be -- a lot of stuff to do for upcoming kamailio 5.1 in the spare time. On the other hand, at the last edition of Astricon, Carsten Bock (one of the ims extensions developer in kamailio) had a presentation about using Asterisk for IMS -- I had to be at the Kamailio booth in Astricon expo area, so I couldn't attend it -- maybe the videos from Astricon are already published and you can watch it, if not, probably they will be released soon.

Hello, Comment inline. Hope I'm helping, Ivo On 11/21/2017 12:32 PM, Amar Tinawi wrote: In order to route the call to Asterisk you should define it as AS/MMtel in your HSS.

From Asterisk perspective the easiest way is S-CSCF to be a SIP trunk. (Note that this may not be 100% true and depends on the design) As far I know there is no DIAMETER/Sh support in Asterisk. Related and to Q below too. You have  2 options in general here, to have or not subscribers in Asterisk. Easiest way is to not. Assuming that all your subscribers are same from service point of view you can handle everything in routing w/o having any subscriber profile in Asterisk. Second option is a matter of design and there is no simple answer. Keep in mind that SIP and IMS services differs. When using * or FreeSWITCH as SIP MMtel w/ SIP clients in IMS env, you can relatively easy implement known SIP services. Implementing MMTel IMS services w/ IMS clients is a different story.

Thanks Ivo I’ll test and report back Many thanks, and any future note or document will be very pleased Cheers Ammar Sent from Mail for Windows 10 From: Ivailo Dobrev Sent: Tuesday, November 21, 2017 4:29 PM To: sr-users(a)lists.kamailio.org Subject: Re: [SR-Users] Kamailio IMS + Asterisk PBX Hello, Comment inline.

Define proper TP and iFC for the subscriber profiles. i followed also Mr Carsten Bock videos on kamailio World conferences for the years 2015 - 2016 - 2017 and he mentioned clearly that any application that talk sip can operate as an AS, and he mentioned Asterisk and FreeSwitch as an example Thanks Mojtaba, i followed this video but the video at the end shows that the users still in offline mode after registration, is that right ? My questions are : - should i configure Asterisk in a way to be AS for kamailio IMS ? For sure you should configure Asterisk to handle originating and terminating call legs from/to S-CSCF. From Asterisk perspective the easiest way is S-CSCF to be a SIP trunk. (Note that this may not be 100% true and depends on the design) - should the users be identified in Asterisk Database in order to make a correlation ? or asterisk can pull users profiles from HSS ? As far I know there is no DIAMETER/Sh support in Asterisk. Related and to Q below too. - Do we have to perform any configuration over HSS to identify sh interface with Asterisk ?   You have  2 options in general here, to have or not subscribers in Asterisk.
