Problems With Multiple SIP Accounts
You can set up two SIP accounts on your WiMAX Device. By default your WiMAX
Device uses SIP account 1 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 port in order to
control which SIP account you are using when placing or receiving calls.
