29.5 Problems With 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.

29.5.1 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 1 or
phone 2, the ZyXEL Device will use SIP account 1.

Figure 220 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 these configuration changes you need to configure
the Analog Phone screen. See
