Manage lines
Section titled “Manage lines”The colored status shows whether a line is connected, connecting, unavailable, or disabled. Reconnect is available for failed or offline registration.
- Drag the handle to reorder lines, or use Move Up and Move Down in the context menu.
- Choose a Default Line for new calls.
- Editing and deleting are disabled during a call.
- Delete Line and Password removes the credentials. Recents remain and continue to show the line name recorded at the time.
Without Pro, only the first line in the order is active. Additional stored lines remain saved but locked. Move the desired line to the first position. If Pro expires during a call on an additional line, the call can finish before the line is unregistered. Eligible lines reconnect when Pro becomes active again.
Ringtone per line
Section titled “Ringtone per line”Every line can use a built-in ringtone. Custom audio files require Pro. If a saved custom file is missing or Pro is inactive, TelefonX temporarily uses the default ringtone. Use Preview Audio before saving.

Section titled “Technical options”Open Data & Diagnostics Connection Help and click Technical Options … for the line. Change these values only when instructed by the provider:
| Option | Purpose |
|---|---|
| Authentication Name | Separate identifier; empty uses the SIP username |
| Registrar | Separate registration server; empty uses Domain / Server |
| Outbound-Proxy | Optional proxy as a host or Host:Port |
