THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY.
A new Flyspray task has been opened. Details are below.
User who did this - Juha Heinanen (jh)
Attached to Project - sip-router
Summary - notify cseq is not incremented
Task Type - Bug Report
Category - Module
Status - New
Assigned To -
Operating System - All
Severity - Medium
Priority - Normal
Reported Version - Development
Due in Version - Undecided
Due Date - Undecided
Details - while doing some presence tests with master i noticed that when presence server
sends notify that terminates subscription due to change in xcap authorization rules and
pres_update_watchers() call, cseq in the notify is same as in previous one.
rfc3261 says in 12.2.1 UAC Behavior:
Requests within a dialog MUST contain strictly monotonically
increasing and contiguous CSeq sequence numbers (increasing-by-one)
in each direction (excepting ACK and CANCEL of course, whose numbers
equal the requests being acknowledged or cancelled).
so this looks like a bug to twinkle (and me). below is sip debug from twinkle (the
subscriber).
