Re: [SR-Users] Kamailio IMS_QOS

Hi Jason, It is always better when code "guru" shares his opinion :) Cheers gents ! On 04/23/2016 01:35 AM, Jason Penton wrote: Hi gents, we do not support the preliminary service information. So for now you can only call Rx_AAR when you have SDP in the replies. So for VoLTE (preconditions), for example you can call on 183 SP whilst using plain SIP you will have to call on the first reply you get that has SDP (either 183SP or 200OK).
