As Brett noted, RFC 3261 seems to allow the branch to be only unique among all requests generated by a UA. But the accepted practice is that it must be unique over all space and time. (Since the UA must be able to generate Call-IDs that are unique over all space and time, it can also generate branch parameters that are, so there is no additional burden on the UA.)
