Monitoring
Dear all,

Both Juniper JTAC and our network partner Axians have restored service stability and stopped internal packet loss.

Any additional changes will be scheduled unless something major happens. We will now move this incident to monitoring status. There is still work to do to get the upgrade to where we want it to be, but service stability is more important.

If you have an issues moving forward please contact SureVoIP Support as usual.

My sincere apologies,

Gavin and the SureVoIP Team.
