• In the SIP ID field, enter the SIP ID provided by your ITSP. For example, if the SIP URI provided by the
ITSP is 12345@abc.com, enter 12345 in this field. Default: Blank.
The SIP ID is the number which remote parties will use to call this SIP Trunk.
The SIP ID may be a number or text consisting of a maximum of 40 characters.
• Enter the Authentication ID (User ID) provided by your ITSP. Default: Blank.
• Enter the Authentication Password provided by your ITSP. Default: Blank.
• Keep the SIP Registration check box enabled.
SETU VFXTH will send the REGISTER message to Registrar proxy or Outbound proxy as applicable.
Clear the check box only if you want to disable registration.
• In the Registrar Server Address: Port field, enter the Registrar Server Address and the Registrar
Server’s listening port for SIP messages. The registrar server address may be an IP address or a
domain. The Registrar Server Address may be of maximum 64 characters. Valid port range: 1025–
65534. Default: 5060.
• If your Service Provider uses outbound proxy for handling voice calls, select the Outbound Proxy
check box. Default: Disabled.
• In the Outbound Proxy Server Address: Port field, enter the Outbound Proxy Server’s IP Address
and the Outbound Proxy Server’s Listening Port for SIP. The Outbound Proxy Server Address may be
of maximum 64 characters. Valid port range:1025–65534. Default: 5060.
• To add ‘rinstance’ in REGISTER message, keep the Add ‘rinstance’ in REGISTER check box
selected.
‘rinstance’ is any random value which can be used by the SETU VFXTH to fetch its own contact
binding, that is, to know the Registration Expiry Timer assigned by the server.
When you enable ‘rinstance’ in Register, SETU VFXTH will generate any random value of 'rinstance'
and include it in the REGISTER message. The system will use the registration expiry timer of that
contact binding.
• By default, the Allowed IP Address for Incoming SIP Message is set to As per Trusted IP Address
table for Proxy SIP Trunk and is non-programmable. You must configure the Trusted IP Address table
to allow incoming calls from specific IP addresses on this SIP Trunk.
Trusted IP Address table stores upto 13 entries, from which last three entries are uneditable. The last
three entries in the table will display the Registrar Server Address:Port or Outbound Proxy Address:
Port and Fallback Registrar Server Address:Port1 and 2 or Fallback Outbound Proxy Server
Address:Port1 and 2, if configured for this SIP Trunk. If you do not configure the Trusted IP Address
table, incoming calls will be allowed from the last three IP Addresses only.
To configure Trusted IP Address table, click Settings .
