Phone keeps ringing

Post by njvijay » Fri Sep 20, 2013 11:12 am

I get call from nowhere. It happens very sporadically. Usually phone callerid shows number like 100, 101, 120 etc., The rings goes on and on forever till I pickup the call (of course no one speak from other end) and disconnect I don't see any call records in call history. Any idea what could be wrong?

If there are no call records in your sipsorcery call history it indicates the calls are not coming through sipsorcery. What's most likely happening is you're getting probed by a VoIP scammer looking for open SIP accounts for them to place fraudulent calls through. The pattern of numbers you are seeing typical of the sipvicious tool which targets Asterisk installations.

The way you can circumvent 99% of the scanners is to change your device's SIP port to something other than the default of UDP 5060.

Thanks Aaron. Your reply helped me to stop receiving unwanted rings. I had done port forwarding in the router setting. Removed the port forwarding and stopped getting phone rings. :D
