In light of last night's problems with VoIP, we have made changes to our SIP platform to make debugging easier in future.
The changes require a full restart to go live, so we will be carrying out this restart out of hours on Thursday evening at 23:00.
This affects all of our call routing too, so will drop calls made through the 'A' server and via IAX2 as well as SIP. Phones will need to re-register.
The outage is not expected to last longer than a couple of minutes, and if anything goes wrong we will roll back the changes.
Sorry for the short notice.
Restart is going to be a little later than anticipated. Sorry, won't be long.
All done. Calls testing and working.
Sorry for any disruption.
