🐞 Regression: tel: URI not handled correctly in Linphone 5.3.0

[kfaroka]

Environment

OS: Windows 11 Pro

Linphone: 5.3.0 (Qt 5.15.2 – Core 5.4.38)

SIP Account: local French operator (Reunion Island)

❗ Issue

Clicking on a link like tel:0123456789 does nothing in Linphone 5.3.0.
Same setup works fine with Linphone 5.2.6.

🔎 Analysis

Regression between 5.2.6 → 5.3.0.
In 5.3.0, the tel: URI is processed by Magic Search instead of being passed to the SIP Core.
The number is treated as a local search (contacts, calls, conferences) and never reaches linphone_core_invite.
In 5.2.6, the Core immediately sends INVITE sip:0123456789@ — expected behavior.

Suspected source: SipAddressesModel.cpp (~line 520).
Core regression likely introduced when refactoring URI handler logic.

✅ Expected behavior

tel: links should trigger an immediate SIP INVITE via the active account (same as 5.2.6). (thanks ChatGPT)
