Calling takes an age to connect

[Wikey2021]

Hi,

We have two EE devices (both iPhones) but they have started to take a long time to dial out and sometimes calls coming in don’t appear either. 

This happens on WiFi Calling and then just on the normal network.

could this be an EE problem locally or maybe and iPhone update.

Can you quantify "a long time" from dialling a call, to receiving a ringtone?

And whether it differs between, say, 01/02/03 numbers and mobiles.

It happens to me when not on WIFI and it seems to be down to the Voice of LTE feature that uses the data connection for calls. Due to having such a bad data connection on EE it worked better when I disabled that feature.

Disabling VoLTE is generally a bad idea, for numerous reasons. It doesn't "use the data connection" in the way that most users would understand.

Data & VoLTE traffic is prioritised differently within the radio equipment. It would be useful to hear back from the OP in this thread, and advise @Wikey2021 on their original query.

Hey, 

so it does it across all numbers, incoming and outgoing. Worst still incoming calls are going to voicemail so we are missing calls. 

In terms of time it can take 30 seconds plus to even do anything when a number is dialled.

It's unusual & unexpected behaviour, I've seen very similar in recent months, which turned out to be a phone fault.

You could eliminate a radio network issue by testing this across multiple areas, ideally several miles apart. I'm unfamiliar with iOS, but if your phones have options to disable 4G or force 2G/3G, that could be a useful experiment - many recent software releases (my Android is in this category) are removing this menu option.

Friends or relatives on EE, would be the other next step.
