Outbound Proxy in Dialog
An outbound proxy server can receive all initiating request messages and route them to the designated destination.
If the device is configured to use an outbound proxy server within a dialog, all SIP request messages from the
device will be sent to the outbound proxy server as a mandatory requirement.
Note: To use this feature, make sure the outbound server has been correctly configured on the device. For more information
on how to configure the outbound server, refer to Server Redundancy.
