I 'm following up from my previous post...
I did not have any call failed issues for 8 days then all of a sudden it started happening again. I did not make any changes to my settings on any equipment.
I tried using a different phone and still had issues.
I'm done wasting my time with Xfinity so I swtiched to another carrier.

I switched from AT&T to xfinity mobile and probably the WORST decision ever! I'ver read through everyone's posts here and I have the same issue. Their customer service is HORRENDOUS! I've tried to get this forum to their attention and they don't give a rat's a**.
I have spent countless hours with their Tier 1 and Tier 2 customer support. Tier 1 thinks they can fix the problem and takes 20-30 minutes trying to get me to Tier 2 after several requests on my end to just transfer me to Tier 2 and skip Tier 1 all together. I have several case numbers going but NOT one person ever gets back to me. I've also requested to have Tier 3 customer support to work on to this issue. Again, I've never heard back from Xfinity.
So I've tried all the xfinity support "recommendations". Reset the network, toggle to/from airplane mode, restore my phone to factory settings (per Apple support), reboot my phone, router and modem, all others everyone here has tried. Xfinity has gone as far as telling that I need a newer phone, use their router and other Xfinity equipment. Sorry but my phone worked just fine with AT&T and I'm not spending $800 just cause you said so. If you can't get this to work, I'd rather spend my money elsewhere.
But I think my last Tier 2 rep may have found a solution. At least I have not received a "Call Failed" message in the last 3 days.
I use an Arris Xfinity modem with a disabled router, Orbi router, and iphone 6. All I did was enable the router on the Arris modem and "unhide" the Wifi so it appears in the list of available networks. It took several hours before I can see it on the list but once it did, I've been receiving calls without the "Call Failed" message.
Hope this works for you guys. Sorry for the long rant just for a simple solution. I hope Xfinity reads this and improve their customer support because I have other issues with them besides this one. One down, 2 to go.
