Hi, Thankyou for the reply. Few more questions please.... Can I be able to enhance Kamailio 4.2.x IMS/RCS based server to implement file transfer feature in it? Quick replies most appreciated. -- View this message in context: http://sip-router.1086192.n5.nabble.com/Regarding-IMS-RCS-complaint-clients… Sent from the Users mailing list archive at Nabble.com.

Hi, just to add a little to this topic and on file transfers: If you look at Camarillo and Garcia-Martin's book "The 3G IP Multimedia Subsystem (IMS)" (often referred to as the "Big yellow book" on IMS, one of the standard books on IMS), it says, that you should announce an MSRP-Relay in the DNS for File-Transfers. This is a feature, you can achieve with Kamailio out of the box. However, the 3rd and latest edition of this book was published in 2011... If you look at the Specs for RCS-e (aka. JOYN), then this is no longer valid. You need to implement some sort of MSRP B2B-UA, you need to implement "Store and forward", as the standard RCS-clients won't trigger a MSRP relay. This feature cannot be achieved with Kamailio at the moment. Also, if you look at the presence stuff associated with RCS-e/JOYN, you will need further enhancements to Kamailio's presence infrastructure, to achieve compability. This is of course a pure RCS-e/Joyn point of view and it does not cover all previous releases of GSMA's RCS specs. However, i also did not come accross any other RCS deployments (neither network nor device) than RCS-e/JOYN.
