In contrast to analog telephony, certain security aspects must be taken into account with VoIP telephony. For example, the simultaneous use of several lines can result in relatively high costs within a short period of time. This can have annoying consequences for both you and us.
To alleviate this problem, we have implemented several safety precautions in our system. Any abuse attacks are actively fended off by various system monitors. We use alphanumeric passwords (ie at least 9 characters, no orderly sequence with upper and lower case letters and / or special characters) on our customers' telephone systems. If you use your own telephone system, we strongly recommend that you use secure passwords (also on all extensions / external telephones).
Setting your limit in your myPhone account provides additional security in this concept. Its primary purpose is to prevent the costs in your account from inadvertently skyrocketing. Secondly, it serves us to keep defaulting payers under control. In both cases, these automatically generated e-mails are continuously checked by us and appropriate measures are initiated.
A telephone system that has been cracked and calls with 30 or more channels via a SIP trunk can cause a delayed reaction of the limit. This can mean that the limit could be exceeded significantly. We charge the account after the call ended. If there are 30 or more ongoing calls and, under certain circumstances, to premium rate numbers, the account can be exceeded by several hundred francs. While this is annoying, it still protects you from even higher costs. Such a case is NOT to be expected if the usual safety precautions are observed. If you have any questions, give us a call. Our specialists will be happy to advise you on this subject.
