These are all valid current registrations, there are params you can adjust for multi reg that will replace previous registrations instead of allowing multiple.

In case of shared lines FS adds contact header of all the lines(or phones with same extension) in 200 OK as shown below due to which all the phones are reading expiry timer from first contact header only.So in below example,Phone re registers after 379 seconds(first contact header) instead of 88 seconds(third contact header) leading to registration expiry on FS.
> Reason why phones are always reading expiry from first contact header is same Public IP(contact is re written by Proxy in front of FS) for all three phones which is confusing phone to identify its own contact header.
