Authorized User Name and Password for SIP
To enable the Registration Options on the Add/Edit Inbound Phone Book, you have to activate Use SIP
Proxy Option on the Call Signaling, SIP Parameters Screen. Then add the IP address for the Primary
Proxy in the SIP Proxy Parameters. This allows you to add a Username and Password to the Inbound
Phone Book entry. The –SS models will only have a password option available.
This feature is used when the MultiVOIP registers with the proxies that support authorization and need
the username, password and the endpoint name to be unique.
The VOIP sends Register request to Registrar for each entry with its configured Username and
Password. When Authentication is enabled for the endpoint, then the registrar/proxy sends “401
Unauthorized/407 Proxy Authentication Required” response when it receives a REGISTER/INVITE
request. Now, the endpoint has to send the authentication details in the Authorization header. In this
header one of the fields is “username”.
Generally proxies accept requests even if both Endpoint Name and Username are same. But some
proxies expect that the Endpoint Name and Username should be different.
To support these proxies, we have the username and password configuration for every inbound phone
book entry which gets registered with a proxy.
If the username and password are not configured in the inbound phone book, then the registration will
happen with the default username and password that are configured in the SIP Call Signaling Page.
Phone Book Save and Reboot
When your Outbound and Inbound Phonebook entries are completed, click on Save Setup in the sidebar menu to
save your configuration. You can change your configuration at any time as needed for your system.
Remember that the initial MultiVOIP setup must be done locally or via the built-in Remote
Configuration/Command Modem using the MultiVOIP program. After the initial configuration is complete, all of
the MultiVOIP units in the VOIP system can be configured, re-configured, and updated from one location using
the MultiVOIP web interface software program or the MultiVOIP program (in conjunction with the built-in modem).
