No, Asterisk is following "expires=600" it received from voxalot, so it will not re-register earlier.

What load?! There are providers who have much more subscribers than voxalot and they are still allowing 60 sec register expirations and they have no problems with OPTIONS or NOTIFY keepalives.
So for me the logical choice will be switch from voxalot to more predictable service. I already replaced all my voxalot URIs I used with e164.org, also changed my DID forwardings to another URI. Very disappointed.
