Registration
Option
Parameters
In an H.323 VOIP system, gateways can register with the system using one of these identifiers: an E.164
identifier, a Tech Prefix identifier, or an H.323 ID identifier.
In a SIP VOIP system, gateways can register with the SIP Proxy.
In an SPP VOIP system, gateways can register with the SPP Registrar VOIP unit.
Authorized User Name and Password for SIP
To enable the Registration Options on the Add/Edit Inbound Phone Book, 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.
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.
