AFAIK, registrar module does not do this.
I believe you can test for Expires and expires parameters in Contact of
REGISTER (SER 2.0 and eval module because you must evaluate a value
below a certain number), add a Min-Expires and statelessly reply with a
423, but I have never tried.
It is probably far easier to add the capability to registar module
controlled by a modparam value.
We gladly accept patches, but send a request to serdev first to hear if
somebody has done it.

Hello all,
I have an issue with some SIP clients (like Linksys SPA 1001) that have not comply with
the "expires" parameter of the Contact header of a "200 OK" Registrar
Response.
My SER conf :
modparam("registrar", "default_expires", 1800)
modparam("registrar", "min_expires", 300)
modparam("registrar", "max_expires", 1800)
Although the (200 OK) response contains the 'expires' parameter :
Contact:
<sip:userb2@192.168.2.10:5061>;expires=300;received="sip:1.2.3.4:5061"
the SIP client ignores it and keeps sending REGISTERs every 5 sec (if configured so).
Is there a way for SER to reject these registrations with (423 Interval Too Brief),
according to RFC3261 - 21.4.17 (423 Interval Too Brief) &
10.3 (Processing REGISTER Requests).
The 'retry_after()' registrar modparam is not my case.
thank you,
Kostas
