Why am I receiving calls from an "Asterisk" caller ID?
If you are receiving calls with “Asterisk” as the caller ID name, the first thing we suggest to check is if the calls appear on your VoIP.ms CDR as incoming calls. If they don't, then we can assure that these calls are not coming from our system, since every call that reaches our system, will appear on your VoIP.ms CDR.
If this is the case, one of the most probable reasons is a direct SIP call to your Asterisk System or Device, for Spam, SIP campaigns or scanners searching for public IP addresses with SIP port open in order to Brute force. Unfortunately this would be beyond our control as these calls never reaches our system.
However, we would like you to follow these suggestions in order to eliminate this inconvenient. If you are using some kind of Asterisk based system, please make sure you disable availability to receive “Anonymous calls” and install proper security.
If you are using an ATA, softphone or IP phone, check for any option to disable these anonymous calls, if there is not, most likely your device don't support “Anonymous calls” by default. Additionally we recommend to verify your router is not set on DMZ mode to make sure your devices and Network are not reachable from public Internet and avoid any unnecessary port forwarding.
Do you offer Calling Card solution ?
We do not offer the calling card solution. However, you can use our DIDs and forward them to a calling card provider if you desire. We also offer the DISA feature (looks a little bit like the calling card feature). Where you call the DID, the system then will ask for a pin number, after entering the caller will be granted with dial tone to make the final call.
