You can select any SIP line as a default for outbound calls. For example, in a Bridged Call Appearance group with private and shared lines, a Boss phone uses shared lines for the majority of calls. As a result, you can set the shared call appearance line as the default.

Your phone administrator can setup any call appearance line as default.

If you perform any call-initiating action and the default call appearance line is available, the phone initiates the call using default line.

If the configured line is busy, the phone uses the following to initiate the call:

• The first available call appearance line for the same user as the first configured call appearance line.

• If the line is unavailable, the phone uses the first available primary line.

• If the primary line is unavailable, the phone uses the first available primary line from another user.
