I would like to be able make and receive calls on my HUAWEI B525s router with a landline telephone as I could with my EE SIM card. Does anyone know the VOIP settings I need?

Hey there @ML-B, we’re sorry to hear you’re having issues with calls.This is likely due to the 3G turn off that began rolling out recently. You can check if this is the case in your area below:https://www.three.co.uk/support/network-and-coverage/coveragePlease read more below on what this is, and what to do:https://community.idmobile.co.uk/3g-200/3g-is-being-switched-off-what-do-i-need-to-do-50979If you have one of the phones from the below list, then 4G VOLTE and Wi-Fi calling should be able to be selected and work, and calls should still work:https://community.idmobile.co.uk/help-with-your-phone-206/what-phone-are-compatible-with-the-id-mobile-network-67490If you have a phone that isn’t on this list, then it may or may not work, but we don’t officially support any phones outside of these and cannot say for sure if it will or not.If the issue persists after following the troubleshooting above and confirming if your phone is approved, then please let us know here so we can investigate further. If your phone isn't listed above, you'll need to upgrade/get a new phone I'm afraid to receive calls. Texts and data should continue to work either way.Thanks,Tyler

Not a reply but adding information, I don’t think it is a VOIP setting at all. Having retried an EE SIM and a LeBara (vodaphone) one that both work correctly I believe it is an Issue with ID or the Threenetwork.
