Open

Name - Type a meaningful name for the Phone Proxy. A best practice is to include the Phone Proxy Type and Protocol used to for registration, for example External UDP Proxy.

Location - This is the Orchestrator that the Phone Proxy is created on.

Zone - This is the zone (logical network) on the Orchestrator that the Phone Proxy is created on. For External Phone Proxies this should be a Public (often Default) zone.

Orchestrator IP - This is the IP address that the SIP based IP phone or softphone will use to register to or through.

Protocol - This is the protocol that will be used to connect to the Orchestrator.

Port - This is the destination port that will be used by the SIP based IP phone or softphone to registration to the Orchestrator. If the Protocol is UDP or TCP then this port must be 5060. If the Protocol is TLS 1.2 then the Port must be 5061. The TCP and TLS 1.2 Protocols use random ephemeral source ports to establish a connection.

Reg Expiry - This field is used to determine how long in seconds that a successful registration should be cached by the Orchestrator. Once this time period has expired the registration will be flushed by the Orchestrator and the IP Phone or softphone will be required to re-register.

Main Registrar - This field contains the name of the Termination Vendor Trunk Group that is used to forward SIP messages to the customer PBX.

Registration Mode - This field determines how the SIP registration messages are processed.

Allowed User Agent - This is a security measure which will do a simple pattern match comparison of the value in this field with the value of the SIP User Agent header in the SIP messages. Up to five comma separated values can be placed in this field. If none of the comma separated entries match the contents of the User Agent the SIP message will be ignored.

Allowed Domain - This is a security measure which will compare the value in this field to the domain portion of the request URI of the SIP messages. If the values do not match the SIP message will be ignored.

Cancel - Click the Cancel button to discard the Add Phone Proxy settings and return to the Phone Proxy Mode page.

Add Phone Proxy Mode - Click the Add Phone Proxy button to create the new Phone Proxy.
