[Serusers] User update on SER

[Felipe Louback]

Hey,

How does SER updates a user location?

For exemple, upon the first REGISTER message, it keeps the location of
the user in a database or so. But this entry has a expire time.

How is this expire time updated? SER updates it upon receiving another
SIP REGISTER or OPTIONS messages?

I know that this update is done, but I am quite confusing about how it is done.

Thanks

Felipe
