[SIPForum-discussion] Should session version in "o=" line be same for 180 ringing and 200 ok message?

[Srivastava, Gaurav]

I found this in RFC 4566 -


"   In general, the "o=" field serves as a globally unique identifier for
   this version of this session description, and the subfields excepting
   the version taken together identify the session irrespective of any
   modifications.
"
There might be some sort of a configuration change in the SIP server handling this to ignore the o line change.

Subject: [SIPForum-discussion] Should session version in "o=" line be same for 180 ringing and 200 ok message?

Hi Guys,

I have one scenario, where my carrier is complaining that their calls are getting disconnected after few milliseconds.
According to their analysis, they are saying that session version in "o=" line  is not same as in 180 ringing and 200 Ok message.
Because of this, they are sending BYE message.

Is this valid reason?

I have checked message, I have not found any difference.
