[sr-dev] Re: Dialog-Module and CSeq tracking

Hello, the CSeq diff variable is for increasing/decrising the CSeq when authentication to next hop is done by Kamailio with uac module/uac_auth(). Only the current CSeq is not enough, because the value has to be set back in reply (I don't remember exactly right now, this might be done with some Via trick) but also readjusted for requests within dialog. So it would be required to keep incoming cseq and outgoing cseq for each direection, but this would be bit tricky to deal with on network races of subsequent requests sent quickly one after the other and the second arrive first. If you need to track differences on both directions, not only towards callee, in my opinion the best is still to have the current incoming cseq and the difference to outgoing to be able to adjust without worrying much about network transmission re-ordering. But I am open to consider other options if people think of better ideas. Then, if it becomes more like a common functionality for the dialog module, the cseq diffs for caller and callee can be made fields in dialog table, not kept as variables.
