long ping lag times causing choppy voip phone service

I am pinging my voip router for my Vonage phone and I am finding lag times of over 120 ms which causes voice dropouts. How can this problem be corrected?

What is the topology between your phone and the router?  how many switches, etc...
If this is at an office, you can look into SD-WAN to reduce latency or upgrade to a higher quality ISP connection, like DIA.
https://SpeedTest.net provides details about your underlying network connection.

Make sure this works first, then post output of mtr or http://winmtr.net/how-to for windows.

This will show your entire topology + where lagging occurs.

Point mtr at your phone IP + also your router + also somewhere like Google.

You'll either see lags or large packet loss percentages. Either one is a VOIP killer.

Also, keep in mind many routers run QOS  (Quality of Service) + defaults may be interjecting lags for your VOIP ports when other network traffic is flowing.

Once you identify problem points, check your QOS settings or just disable QOS altogether + see if mtr shows problem has cleared.

The router connects directly by wire to a Vonage box. The ping is testing the communication between the router and the box.

This is home based system.

I am going to download MTR and run it.
This sounds like your VOIP box may have a problem.

A direct connect shouldn't (to me) have any lag.

Give Vonage a call about this. They're very good about replacing defective equipment.

Does skype depend on at least one computer servicing it actively? Can it support multiple Dect phones?
Skype doesn't use handsets normally. I suppose you might find some that worked.

Skype is a computer/phone/tablet client.
