question

Possible port blocking?  The phone will use UDP 5060 - 5090

That would be the first place I would look.

Has it ever worked?

Chuck, 
Can you explain or point us to where we need to go to see if port blocking is taking place?
I am having the same issues on 4 phones. Intermittent service, dropped calls and not being able to either hear the other person or have them hear us. It is not an internet issue as we are up live on everything else. It is not a band width issue. We have qos with our internet and have been assured there are no issues in our area and have also verified with a tracer on the line that there are no issues.

I spent over an hour on the phone with Ring Central earlier today.  I was able to get a sporadic connection on the wireless router, which has four LAN ports (which we use for the XBox, smart tv, etc., simultaneously), however on the modem I have downstairs, I can't get anything; the phone doesn't even display an IP address.  Ring Central said there was nothing further that they can do.  I have to try to contact my internet provider (RC tried to call 3X but kept getting disconnected).  

It was suggested that perhaps the modem I have downstairs was only able to accommodate one device at a time or that it was set up to only work with the first device plugged into it.  Either of those is unlikely, especially given I received the modem from my parents when they upgraded (it's less than a year old), and thus it had previously had other devices installed, and the computer is able to access the internet through the phone but the phone doesn't work - even when the phone was the only thing plugged into the modem.

In short, I've tried three different LAN cables, a port on a wireless router and a modem on separate levels of the house.  I've also tried an ethernet switch.  The router and modem currently work with other devices plugged into them, using those same LAN cables. The computer connected to the internet with the switch.  The phone has power.  It worked briefly and then would cut out on the wireless router.  

I'm really frustrated.  For now, I've installed the app and have the phone forwarding to my cell through the app, but this is not a long-term solution.

Any other ideas?

Absolutely not a long term solution, I run a customer service operation and to have my people on their cell phones is ludicrous. Answers are lacking from Ring Central and I am not impressed. I am looking into getting rid of the IP system altogether now and go back to pots lines or cable lines and use RC for what it was good for, switching calls. I am ripped, this is taking up too much of my time.

Justin, these port triggering / port forwarding settings are on the router.  I ususally start with out the settings to see if the phone work and only put them in if I am having connection issues.  Usually if the ports are blocked, then the phone will never work.

What type of phone is being used?  make and model please.  Also did the phones come from RC or 3rd party.

Lots of variables here so lay out a few details so I could try and help

Thanks
