I'm being slammed with voip calls, perhaps an error in setup on my end or theirs
JeffDB:
Things seemed to be going pretty well for me for awhile when I set up my Obi 1062. I had a google # on line 1, another google # on line 6 & a free incoming Callcentric # on line 3.
Then one evening I started getting call after call after call on line 3. It rang incessantly all night & into the morning. I picked it up & no one would be on the line... then it would call back almost immediately. I was getting hundreds of calls & they didn't have any legitimate phone # on the caller id. If I recall, they showed up as something like V395787965...
I checked with Callcentric but there were no numbers showing up as incoming calls. I posted a support ticket and was told that it wasn't coming through their servers. If I understood correctly, they said it might be some sort of misconfiguration in the setup on the Obihai, or that there might be a way to re-configure it to prevent that.
Then it stopped on its own & I forgot about it, but periodically it would start up again... maybe a few days or a week or two later.
Now I'm getting the four middle lines lighting up continuously... lines 2 through 5, which are unused now that Callcentric discontinued their free incoming line service.
Any help, recommendations would be appreciated.

How is the Obi connected to the internet?
Do you have a router/firewall between the Obi and the modem?

It is connected via an ethernet cable to an AT&T modem/router.
I assume it has a built in firewall.

It doesn't sound like it.
You probably need a router between the modem and your equipment

These are SIP calls routed to your public IP and a port number commonly used by SIP devices.
