When I say "no" to the "record phone call" prompt, or I hide the prompt by pressing the back or home button, no phone call is record and no webhook is called.
Can you add a setting that says: "always call webhook after each phone call" (ignoring the user prompt)
For me, this allows me to record locally when I want it (that's what the user prompt is for, I am not interested into having all phone calls locally on my phone), and store the phone call remotely ALL the time for analytic purposes and not worried about not forgetting the user prompt. I know I can disable the prompt, but I do not want to do that.
Small bonus (hope this never happens): when my phone is nicked/stolen and he does a phone call, I have evidence of what is going on/who he is calling to (I do also have other app to see where the phone is). He will not press 'record phone call' as you may guess :-)
