Please help! How to stop Facetime from opening automatically on a phone link? Used to be a Call option

Not sure what happened however we had a phone link that when clicked would open an option to Call or Facetime … my client has just advised there is no option - it only Facetimes?!

I posted this yesterday and unfortunately no replies.
Can anyone advise why or a way around this? I’m a newbie here so please excuse my ignorance.

Thanks in advance,

Rachel

Probably somehow the default app handler was changed on the phone.

Thank you so much for replying samliew !!
Sorry I should I have indicated this is occuring on the desktop.
How would I fix the app handler? Again, excuse my ignorance.
