For everyone's protection and to ensure network performance, we continually monitor for and automatically protect against possible attacks.
Our network will not block IPs for connecting from more than one location or from more than one device (this will cause other issues, like not being able to receive incoming calls). If you wish to connect from more than one device at a time, a Clone Device is required (more details on Clone Devices, and to order, can be found in the User Webportal
Our network will only automatically block IP addresses when it detects possible intrusion or attacks. Such conditions that would trigger an IP to be blocked are:
- Too many failed registration attempts (due to incorrect username and/or password).
- Too frequent registration (or re-register) requests
Within the registrations responses, a minimum re-register time exists. Devices and apps must abide by this, as it protects the network from being hammered by hackers. If using a softphone, use known and reputable applications (as they will tend to abide by the SIP RFC policies that are in place).
- Too many connection attempts to invalid ports
Although your local SIP port can be anything you wish (The default local port is 5060. We recommend local port 25060, as this often gets around many router SIP ALG issues), the SIP server port must be 5060.
