Expire: Expire time for the registration message sending. Default is 3600 seconds. Your VoIP provider
may advise an alternate time period.
User Domain/Realm: Set the domain name for the VoIP SIP proxy server if required by your provider.
This is often the same as the registrar address, and may be left blank if this is the case.
Outbound Proxy Address: Indicate the VoIP SIP outbound proxy server IP address.
This parameter may useful when VoIP device is behind a NAT firewall. The field may be left blank if same
as Registrar address.
Outbound Proxy Port: Specify the port of the VoIP SIP outbound proxy on which it will listen for
messages. Default is 5060.
Note:
Registrar Address, User Domain/Realm and Outbound Proxy Address are a single address for many
providers. In this case the latter two may be left blank.
Phone Number: This parameter holds the registration ID (SIP number) of the user within the VoIP SIP
registrar.
Authentication Username: Usually the same as the Phone Number above.
Authentication Password: This parameter holds the password used for authentication within VoIP SIP
registrar.
Confirm Password:
Re-enter the password for confirmation.
Display Name:
Displayed name of the Profile eg in Phone Port screen.
Direct In Dial:
Specify the FXS Port to which incoming calls to this profile will be directed.
Default is None, and calls may be directed to either FXS1 (Phone Port 1) or FXS2 (Phone Port 2).
Notes:
1. The VSP accounts defined for each Phone Port (FXS port) in the VoIP General Settings screen will be
registered with the VSP in order to allow incoming calls to be directed to the correct FXS port and thus ring
the attached phone.
2. In Firmware 5.52G and later, User Defined Profiles that have a FXS port selected will also be registered
with the VSP to allow incoming calls to be directed to the relevant Phone Port.
3. Thus, incoming calls may be directed to a particular Phone Port from several VSPs, including the one
registered directly to the port, and also any User Defined Profiles that have also assigned the DID setting
to that port.
4. Avoid duplicate definitions of VSP accounts in User Defined Profiles and directly in the General Settings
screen as this may cause improper operation.
5. Registrations for VSP accounts will be recorded in the Event Log.
