These calls are to the polycomm desk phone only, softphone/RC call controller is unaffected.
This is a variation on a problem that I had with the softphone / RC call controller but i changed the listening port per suggestion in community forum. softphone issue appears fixed.
My polycomm phone, however, gets these calls all the time, but never with this unrelenting frequency. NB, they appear in the phone's own call log, not in the call controller or in my online account activity log.
i need this fixed asap. it is either a security issue, SIP sniffing, or your system and you haven provided me with the necessary settings for the typical router firewall.
I have the desk phone plugged into a gigbit network and access to the internet through AT&T uverse max and my usability of the ringcentral service has been
good.
Another call from "1000" as I typing this. . . and another, taking up my rollover line, Who can help?

they need to move the phone off of 5060.
Only support could make this change as the end user could make the change on the soft phone.
I have seen this solve the problem
Keep us in the loop
Thanks

So the message is suck it up and too bad. 90+ calls! That's right, 90+ calls.
Very disappointing, Ringcental. Seems like they would have a fix for this problem when it can be resolved by changing a port on the softphone/call controller.
Thank you, however, for your help, Chuck.
This was, allegedly, escalated to tier 3 support, whatever that means.

In my conversations it is something local on the network that is causing the issue.
I talk to a lot of people but is your phone network on its own VLAN?
If there is a way to isolate the phones so that other local network traffic is not causing an issue.
Let me know
You could also contact me directly so we could figure something out.

the phone is not on its own vlan. just router to switch and devices and desktop into switch. nothing fancy other than hp laser jet, desktop, etc and phone. all using
dhcp not static ip.
so you are thinking isolate the phone on vlan?

Correct me if I am wrong but these calls are NOT showing up in the activity login on line. That tells me that the call is not originating from the RC system but the device it self is picking up something on the network.
Networks sounds simple so would you be able to just isolate the phone for a period of time to see if the problem still exists?
It is obviously something that is not easy to find so that is how I would move to solve this issue.
know what I mean?

I wonder why tier 3 support hasn't seen?

I've had a personal VOIP line with a couple other providers for 8+ years and never had such a problem.

I have been trying to get a good router config from RC to help on the lock down but any good router person could adjust the firewall to ignore these requests.
This is what I would try to do. This is a hard thing to test as not all people have this issue. Since you are having it playing with the Firewall rules until it stops will help.
Some other VOIP providers use VPN type connections from the phone to theis service and that will not allow this stuff to happen..
RC should consider this.
Let us know if you are able to get a good FW rules to only let that traffic through

they don't even reply to my case. I have the router configured correctly, and proper set up requires an update or setting change to the polycom phone. RC is not willing, not interested, or not able to make this change.
And did I mention they have ignored my case? And they don't respond to the issue here on the forums.

However, since posting, I was going through my router settings with a fine tooth comb and found something called "SIP ALG". After a bit of googling I found it is generally recommended to turn that off (on by default on my router).
Disabling has negated the need to have a forwarded port on my router (was needed for incoming calls to work). Now I've been able to close off the port so that my phone establishes communication with the endpoint properly thereby opening up communication only to RC on that port. Only time will tell but I'm hopeful this will work. I will follow-up in a few days to report this a success or failure. Thanks!

I'll take a look at Will Hunter's advice. If I remember right, the Polycom installation actually told us to enable SIP ALG.
My question to Will is - it almost sounds like this could cause a problem with incoming calls?? Or is that handled through a continuous link between the phone and the RC endpoint that is/was initially established by the phone?

My understanding is that when the phone boots up, it establishes a connection to the RC endpoint which in turn provides communication back to the phone from RC (and only RC) through that port, therefore no need for port forwarding. Port forwarding is what opened my phone up to the ghost calls. My best guess is that the SIP ALG was somehow preventing the initial "handshake" from occurring properly. I also read that SIP ALG is poorly implemented in many consumer routers... so maybe there is something to that.
All I know is my RC line has been on par with any landline I've used since the change. Good luck!

Turning off the port triggering solved the ghost call problem. Now, legit inbound calls are hit-and-miss so they must rely at least partly on the port triggering and/or a recent solid socket connection with the RC servers. Sometimes the phone rings, sometimes I get the forward to my cell without the phone ringing at all. It's still not a good solution, and I'm still not happy. I've NEVER received an answer or suggestion from RC on this even though I've asked more than once.
As I said before, the phone itself is capable of blocking out these ghost triggers. RC has it locked down to the point I can't get in. I'd be happy if they just let me know how to ssh or telnet in to the phone and give me the needed server address ranges so I can set the phone's iptables appropriately.
I'm not happy. The IP phone they pushed me to upgrade to has limited value. I'm very busy with other things, but if/when I fin a better solution I don't have a problem giving RC the boot at this point.
