I will be working from home soon. The company requires internet and home phone service. I've bundled the phone service with my internet provider. I want to know if I can use my current Net gear Nighthawk Modem/router all-in-one model version NETGEAR C6900
https://www.netgear.com/home/products/networking/cable-modems-routers/C6900.aspx
 
Note, It does not have a phone jack/port on the back of it. It only has Ethernet connections. Is there a specialized VOIP adapter or some third party device add-on that I can purchase to connect to the back of my current modem that acts like a phone jack/phone system for VOIP? I really like my gaming modem/router and don't want to switch out to another lesser quality modem/router with a phone jack built into the modem. What are my options and what would really works for the hardware configuration I'm seeking. Does it even exist? I heard that I might need a new router/modem with the built in phone support. I'm not sure but if there is such a device that would work with my current setup that would be great.
 
Options for consideration is this device.

Who is your ISP? You should probably be asking them. With my current ISP, I had a choice of them supplying just a modem, or a modem & router combined. I use their modem only (which also provides the phone jack and the cable tv jack), and then I connect my router to the modem and run all our wireless devices and hardwired desktops through my own router.
 

These are all great suggestions and tips. I look forward to doing so much with the information provided. Thank you! :)

Comcast is my provider.

One solution is to ask your cable provider for a telephone/EMTA modem, and you can still use your C6900 for internet access. I did this at my apartment with my own Arris modem combined with an EMTA modem provided by my ISP. You will need a coax connection to both modems however, so either you will need to have them run another coax line, or split your existing coax behind the modem using a cable splitter. Keep in mind if you go the splitter route, you will have some signal loss which could potentially impact internet performance.

If they do then I'm also very certain they would have me pay a monthly lease rental fee for any related EMTA Modem hardware.

Depends on Comcast's terms. I have Spectrum and was not charged for the EMTA equipment as they do not have a modem rental fee.

with cable you have to have 2 different ones a router ones a phone modem with dsl it's all built into one modem of course I know the speeds are worse.
 
ps: I work for phone company while taking some spectrum modems loose I've noticed some are built into one now i'm sure your isp has them to!

Best option would be to rent the Comcast modem. That would give you internet and phone. Since you own the Nighthawk I would probably use that as the router and just use the Comcast Modem though it will be a modem and router.

The Nighthawk would need to have a WAN port to be used as a router off the Comcast modem. I was thinking about suggesting this too, but the Nighthawk only has LAN ports. If you connect one of the LAN ports off the Nighthawk to the modem's ethernet port it won't work the way you think it will. Plus, since they are both combo units, there would be double NAT and DHCP (bad), so he would need to put the Comcast modem into bridge mode - further compounding the issue that a router with WAN port is required. Otherwise, it would be the same concept as plugging a modem directly to a switch - it won't function the way an actual router would.
 
The only way it would work, is if the Netgear has some sort of intelligent detection and "converts" its LAN port to a WAN port when it sees the modem but I found nothing in the manual that suggests it can do this.

still better to sign up with one of the home viop providers, just about every one of them include a cisco SPA2102 ATA device that you connect to your router, service with unlimited calling runs about $9 per month when you pay for a year ( so about $160 payment and your good for a year)
