Multiple SIP Accounts
You can set up two SIP accounts on your ZyXEL Device and your ZyXEL Device is
equipped with two phone ports. By default your ZyXEL Device uses SIP account 1
with both phone ports for outgoing calls, and it uses SIP accounts 1 and 2 for
incoming calls. With this setting, you always use SIP account 1 for your outgoing
calls and you cannot distinguish which SIP account the calls are coming in
through. If you want to control the use of different dialing plans for accounting
purposes or other reasons, you need to configure your phone ports in order to
control which SIP account you are using when placing or receiving calls.
16.4.1
Outgoing Calls
The following figure represents the default behavior of your ZyXEL Device when
two SIP accounts are configured and you are using two phones. When you place a
call from phone port 1 or phone port 2, the ZyXEL Device will use SIP account 1.
Figure 95
Outgoing Calls: Default
In the next example, phone port 1 is configured to use SIP account 1 and phone
port 2 is configured to use SIP account 2. In this case, every time you place a call
through phone port 1, you are using your SIP account 1. Similarly, every time you
place a call through phone port 2, you are using your SIP account 2. To apply
