How about using a global parameter like:

1.3.3. max_expires (integer)

   The maximum expires value of a Contact, values higher than
   this maximum will be automatically set to the maximum. Value 0
   disables the checking.

   Default value is 0.

   Example 1-3. Set max_expires parameter
...
modparam("registrar", "max_expires", 120)
