    We have added some quite sensitive checks to try and detect VoIP attacks, i.e. where someone has compromised your call server or obtained your SIP details and is using them. These types of attacks can cause rather large unexpected bills. They are quite rare for us as we have a default low call rate allowed on international calls, but some customers with these rates set higher have had some attacks lately. The new measures should not cause any problems, but we are monitoring the situation closely. If your account is locked down you will get a recorded message when trying to make calls, and an email. You can unlock the account from our control pages without the need to contact us first. Obviously, if you do get locked down and a warning, please do check the call records to confirm this is not an attack. We are able to adjust the thresholds we have set if we find it is too sensitive. As these new features are only on the new call server (voiceless) we recommend people move to the new server. Once you have moved to the new server you will not be able to make calls via the old call servers so that the new security measures cannot be bypassed.
