Is there a list of which system changes needs a reset

Going to test this out right now!

Just Upgraded as the new features were so attractive.

Vmail to email page now says my email addresses are invalid. seems happy with any address with only one . however: eg .com

This isn't a region pack thing is it?


I have a similar problem to Daniel, but with email addresses ending Seems a bit of a basic error to assume the world only uses .com email addresses!

The 'new features' may be useful to a limited number of users - 'hot phones', 'call restrictions' etc, but there is still no sign of the basic functionality that everyone on these forums keeps requesting - automatic outbound call routing without having to press a steering digit, the ability to simply redial a missed call (for example), without editing the number to append a steering digit, softphone support and remote office (VPN) support.

Extremely disappointed with the limited improvements, given how long we have been waiting for this update.


Hi Clive;

Thanks for your feedback. About the voice to email issue, we have opened an emergency defect and will provide a fix over the cloud very soon. About the new features, this is by no means the latest feature set we are adding. Next major release 2.3 will incorporate most of the features you are looking for, so we appreciate your patience. We are still working out the schedule details, will share as soon as committed.

Glad to see p-time parameters included in SIP settings beginning with FW release 2.2 (which has been currently pulled due to other bugs) so no need for PMF. Are there any plans to add registration timer parameter which can be changed?

HI Haresh,

Just curious ...What is the use case?  The service provider can always respond back with a lower expires time and the UC320W will honor it.  We have NAT keep alive mechanisms.


The ITSP reset the trunk during troubleshooting it was taking a longer time for the UC320 re-register and they asked if I could lower the timer. On that note, may be a way on UC320 to reset just the trunk other than rebooting the whole box.

Thanks Haresh.  Will look into adding a manual reregister feature.
