SIP: Protocol - Select Default SIP/Softphone App

Hope someone could help me with this, as I can't figure out how to select default SIP app on the iPhone, if multiple SIP/Softphone apps are installed.

Reason behind is that we have a work website where on click of the number opens up Bria Solo SIP application to initiate the call.

Code behind: <a href="sip:0402123456">Call 0402123456</a>;

However, if on the iPhone I have multiple SIP apps, like Bria Solo, Zoiper, etc. it always initiates Zoiper by default. Other users reported if they have Bria Solo and Skype on the phone it triggers Skype.

Is there a way to select default SIP/Softphone app on iPhone iOS version 17.6 or above.

thanks
