How to increase number of rings on iPhone 15 before going to messaging.

[Leatherman]

The current 3 rings is insufficient for me.  I have tried several methods without success.  Anyone know one that works?  Thanks.

Gentlemen. 
I have found the answer to my problem regarding the number of rings an iPhone will ring before going to messaging. 
It is totally dependent on the default setting of our network provider. The iPhone will allow up to 45 seconds of ring time and the set up is **61*101**45#. I. tried this but it failed so I tried 30 seconds which also failed. 
I was successful inputting 25 seconds and this does almost give me a fourth ring, which is helpful, but still not enough for me. 
In the above code the 101  relates to Apple phones and I believe 100 is for Android. 

SO COME ON EE RAISE YOUR DEFAULT SETTING TO AT LEAST 30secs PLEASE.

This is inconvenient, particularly when a call is very important such as elderly relatives in need. It's also annoying to miss the call at other times. Is there any good reason why this can't be increased?

I'm curious how a network is supposed to know when a call is super-important and when it's just an average call?

Presumably different timers should apply to mega-important callers than average callers.

My diverts are set to 30 seconds with no problem?!?

The code to use is **61*<whatever number you want to divert to>*11*nn# then dial that number.

nn = the number of seconds you want to elapse before diverting to the number you’ve set, in 5 second increments from 05 to 30 seconds.

Example:

So if Joe Blogg’s number was 01234 567890 - and you wanted to divert calls to him after 20 seconds, you would use

**61*01234567890*11*20# then press the dial button.

If that doesn’t work, then you’ll need a “Network Refresh” on your sim, which can be actioned via Customer Services.
