9.7 Configuring Micro PBX Line Settings
Before you can make phone calls, you need to configure lines. Lines are logical SIP ID
numbers (i.e., telephone numbers) which are registered to a SIP proxy server and for
which you are charged for calls you make on it.
With a micro PBX line setting configuration, you can associate any phone extension to
any line.
• When you receive an incoming call, all the registered extensions on the line ring,
and you can answer from any one of them. When you do answer, the other
extensions stop ringing.
• If you receive another incoming call when you already have an established call on
one extension, all the idle extensions ring, and the busy extension hears a call
waiting tone.
• You can make outgoing calls from any of the extensions, using the first line of this
extension.
• You can make multiple concurrent calls (i.e., each extension makes a call to a
different destination and at the same time).
Notes:
• You can perform call hold, call transfer, and three-way conferencing between the
internal extensions.
• Each SIP account (proxy) supports up to four concurrent calls.
• The device supports up to two concurrent HD VoIP conversations when using the
G.722 or AMR-WB coders.
To configure lines:
1. On the 'Voice Over IP' screen, click the Line Settings tab; the following screen
appears.
