8.2.2 SIP Related Function
In this section, you set up your own SIP settings. When you apply for an
account, your SIP service provider will give you an Account Name or user
name, SIP Registrar, Proxy, and Domain name. (The last three might be
the same in some case). Then you can tell your folks your SIP Address as
in Account Name@ Domain name
As Vigor VoIP Router is turned on, it will first register with Registrar using
AuthorizationUser@Domain/Realm. After that, your call will be bypassed
by SIP Proxy to the destination using AccountName@Domain/Realm as
identity.
VoIP Setup
Although the Loop Through function provides
convenient live lines for your call, you might prefer
None for directing all calls via Internet. Please be
reminded that you can still make the call via PSTN by
manually dialing "#0" first.
This will also work if you may wish to know in which
way every call dials out so that you can count how
much they save before receiving the phone bill.
