[Serdev] FW: [Serusers] limiting expires time

[Chris Crawford]

I will put the enhancement into the registrar module.  IMHO it should be
part of the registrar module and not a core option, so that it could be
set on a user-by-user basis.  For instance, there may be a group (ACLs)
associated with limiting user registration times (normal users).  There
also may be another group associated with 'permanent' registration times
(gateways, admins, etc.).  It allows more flexibility with each
registration request.

Below is the functionality that can be expected:

1- If a maximum expires is set, then each contact in the 200 reply that
has an expires time greater than the max will be set to the maximum
expires.
2- If the expires header has a time greater than the configured max,
then the 200 reply header will be set to the maximum expires.

Is this reasonable?  Thoughts?
