Terrible VOIP call performance, constant drops, lags every few seconds during any call, huge ping drops. Using any VOIP application Microsoft Teams, Discord, Skype any ... all bad.

Start and period of the disturbance
Constantly failing for the last few months (semi unbearable) rebooting router helps for an hour or 2, but recently service dropped completely for a full 24hours. (26th August 2021 11.00 approx) once the connection restored a day later, every 3 - 5 seconds, it will drop out for 2 - 3 seconds. So, no communication happens, all VOIP useless. Ping or sustained connection to any game service is terrible.
Upload a screenshot of the signal values 

What measures were carried out by the fault hotline (available at 0800-5266625 for Vodafone Kabel Deutschland or 0221/46619100 for Vodafone West)?
- Denied there was a problem to begin with, then eventually admitted there was no service in our approximate location, then took a day to repair it. No help on the VOIP quality issues. Specifically got worse after the "total loss repair". But its always been below par on VOIP quality.

Good morning abigail,

Thank you for your update on the technician visit.

Unfortunately, it is not possible to switch to a pure IPv4 address.  You need a business contract for this. What we can try in any case is the changeover to dual stack. However, it is important that you need either our Power Upload (2.99 euros per month) or our Homebox Option (incl. Fritz!Box 6660).

Please be so kind and let us know if you agree and which of the requirements you would like to book so that we can then switch to Dual Stack.

Kind regards

R4mona
