VSP (SIP Proxy Server) Settings (continued)
This is optional. An outbound proxy server handles SIP call signaling as a standard SIP proxy
server would. Furthermore, it receives and transmits phone conversation traffic (media) in
between two talking VoIP devices. This option tells VoiceCom90 to send and receive all SIP
packets to the destined outbound proxy server rather than the remote VoIP device. This might
helps VoIP calls to pass through any NAT protected network without additional settings or
techniques. Please make sure your VoIP service provider supports outbound proxy services
before enable it.
Note: Make sure your Voice Service Provider requires this feature before enable it. VSP
gives parameters.
