Hello,
We are running Kamailio 3.1.5 and using the acc module to generate CDRs and provide reporting information. We have a requirement to report ring time and we do this by accounting on early media for 183 provisional responses. Unfortunately
we have a couple of customer PBX’s that cannot provide a SDP with the ringing response. i.e they just respond with a ‘180 ringing’.
My understanding of the module is that the “early_media” parameter is looking for a SDP in either a 180 or 183 response before accounting. Although it may be possible to account the 180 without SDP using the acc module I cannot find
anything obvious in the documentation.
If it is possible could someone point me in the right direction or suggest a creative solution, otherwise can I ask that this functionality be introduced.
Many Thanks.
Steve Dodge.
