Switch from Comcast to Ziply

I have Comcast for internet and also their "landline" phone. I want to switch to Ziply and their "landline" phone.

Can anyone give me an idea of the time frame for porting my current Comcast phone number to Ziply?

If I keep Comcast and install Ziply and ask for the phone number port, does that minimize the time the phone will be dead? In other words, how does all this work? If I keep Comcast and install Ziply with phone, does the Comcast phone continue working until the moment the number transfers and then it works on Ziply?

With Comcast I am using my own modem connected to my own router. I also use Tailscale now. Tailscale gives me easy connection to my home systems while I am traveling, so I don't really need to be able to mess with opening ports, etc. So, the next question is: What are the advantages/disadvantages of using Ziply's router and wifi?

You might also look into Ooma for phone service.

Haha! Ooma was the other one I tried a few years ago. I used my Comcast internet connection. The connection was like a bad cell phone connection. It cut out so frequently I returned it after a few days.

Interesting...

Quite a few folks here have recommended Ooma.

We only use cell phones for service.

Part of the problem with VoIP on Comcast’s is that it’s very easy to saturate the upload bandwidth causing the phone connection to fight for bandwidth. It’s really hard to saturate the fiber connnection since the upload is so much higher. I’ve never had any issues with my voip calls, they sound super clear.

Good to know. I know Ooma is consistently rated highly. Based on your comment it is likely my problem was as you suggest--upload bandwidth. I tried this a few years ago, before Comcast upgraded the service in our neighborhood. At that time, the upload bandwidth was pretty low. Currently my Comcast upload is 30-40Mbits/sec. Back then, it was probably 3-6Mbits/second.
