• In Outbound Proxy Server Address: Port, 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 range is 1025 to 65534. Default: 5060.
• To add 'rinstance' in REGISTER message, keep the Add 'rinstance' in REGISTER check box
enabled.
'rinstance' is any random value which can be used by SARVAM UMG to fetch its own contact binding,
that is, to know the Registration Expiry Timer assigned by the server.
When you enable 'rinstance' in Register, SARVAM UMG 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.

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.
