Dear List
I'm currently facing an issue with a carrier whereby they are complaining
that the via header branch parameter (sip.Via.branch == "z9hG4bKcydzigwkX")
in the ACK messages is not unique which results in some calls being
successful and some terminating after 20 seconds as their sip proxy
determines it as a duplicate request. Is there a way to make the via header
branch parameter in the ACK message unique across every transaction?
Thanking you in advance for your assistance.
Phillip
