[Freeswitch-users] NOTIFY's Cseq too high?

[Michael Jerris]

actually that is the 31 bit max, not the 32 bit... but thats a different story.  There is now a patch in tree that fixes this issue.

> Yes, you are correct, all devices freaked out until they we rebooted.  The issue appears to be that the Cseq exceeded 32bit max.  Before this change I was seeing Cseq values as 2147483647 which is 32bit max.  As soon as the dust clears I’ll file a jira.  I don’t really know what a good upgrade path might be but it seems the calculation method has to change.
