[Bug report]

• Jami version: 3.89

• Distribution channel : [App Store]

• Account-related devices: [multiple]

• State of the app when the bug appears: [foreground]

• Can you reproduce the bug: [at will]

Steps to reproduce (STR):

1. Have a Jami account linked to multiple devices. Ensure that this account has an iOS device added as a contact.
2. While the Jami app on the iOS device is in the background, place a call to it.
3. The call screen will appear on the iOS device, but the contact will be displayed as "Unknown".
4. If the call is accepted at this point, it will fail.
5. After 5–10 seconds, the call screen will update to show the correct contact name.
6. If the call is accepted at this point, it will connect successfully.

Note: This issue is more likely to occur when the account has multiple linked devices. With only a single linked device, the issue does not appear.
