Pl find the below snippet in RFC 5628!
* It should remove any temporary GRUUs with a "callid" attribute
value different from that in the value of the "callid"
attribute of the <contact>, or with a "cseq" attribute with
value less than the value of the "first-cseq" attribute of the
<temp-gruu>.
It means that the Registrar shall invalidate the temporary GRUU, when a
certain
limit is reached. And, the limit shall be conveyed to UE using reg-ev
package.

Mohammed Hanifa
