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

[Spencer Thomason]

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.

I guess we do have to limit the value to 32bits:
8.1.1.5 CSeq

   The CSeq header field serves as a way to identify and order
   transactions.  It consists of a sequence number and a method.  The
   method MUST match that of the request.  For non-REGISTER requests
   outside of a dialog, the sequence number value is arbitrary.  The
   sequence number value MUST be expressible as a 32-bit unsigned
   integer and MUST be less than 2**31.  As long as it follows the above
   guidelines, a client may use any mechanism it would like to select
   CSeq header field values.

Thanks,
Spencer
