BT Smart hub2 + mesh wifi Mobile phone voice transmission dropouts

We are getting poor quality iPhone calls when at home making/ receiving mobile calls whilst connected to the router/ mesh system with our iPhones. The issue is voice dropouts. When disabling wifi, the calls have no voice dropouts. The calls stay connected but we miss words in the conversations. Are there any known issues? causes? of this. VOIP calls with the BT phone are not affected with this issue.

Hi @carlosfandango

Thanks for coming to the community.

If you're having poor call quality when making and receiving calls on the iPhones, please get in touch with our broadband technical support guides and they can run some troubleshooting and get this looked into for you.

Thanks.

Leanne.

To me, this sounds like interference with Wi-Fi calling or poor mesh network connectivity. You should try updating your router or mesh network firmware.
Be sure to make sure Wi-Fi calling is enabled on your iPhones, and if possible, assign a separate SSID for the phones or adjust the range settings to reduce congestion.
