NAT Keep-Alive and Registration Expires

[melcon]

Is there a way to setup a sort of NAT keep-alive, so the SBC would send OPTIONS to the remote workers registered in order to keep the NAT hole open on the far-end?

Also, how to tweak the Maximum Expire time for registrations? For remote workers it might be needed to enforce a lower expire time to they would re-register more often.

Best regards

Hi

You can set default, minimum, and maximum contact expiration when you creating a new SIP registration Domain. We have a Keep-Alive mechanism for the NAPS not for registered users.
