NethLink and Phone Island: Closing Second Conference Call Breaks Previous Call

[viktec]

Description
When placing a second call during a conference and the second participant does not answer, manually closing the second call puts the interface in a limbo state: the previous call is no longer visible in the Phone Island and cannot be resumed. To continue the conversation, the first participant must be called again manually.

---

Steps to reproduce

1. Make a call to a first user (e.g., Tizio)

2. Start the conference

3. Add a second participant (e.g., Caio)

4. Caio doesn't answer, so manually close the second call

5. Observe the behavior of the Phone Island

---

Expected behavior
The Phone Island should return to the previous call with the first user, allowing the ongoing conversation or conference to continue without disruption.

---

Actual behavior
The Phone Island disappears or freezes, and the ongoing call with the first participant is no longer accessible. The only way to resume the conversation is to call the first user again.
