[OpenSIPS-Users] is_contact_registered - not working as expected

[Bogdan-Andrei Iancu]

In this case, the function will perform a string matching between the 
first valid contact URI from the message and the registered contacts 
(the `Contact` field). Again, it is a string matching over the entire 
SIP URI.

So far, based on your logs, I would say they should match. Could you 
doublecheck again ?
