One Chunnel GSM VoIP Gateway
22
The GoIP Gateway supports one Backup Server as an alternative to the main server.
Once registration to the main server fails, the GoIP Gateway will try to register to the
Backup Server.
I） Outbound Proxy
OutBound proxies are devices that will forward SIP signaling (and frequently
RTP media traffic too). OutBound proxies are used for a number of reasons,
including, firewall traversal – both in parallel with a firewall and situated in the
Internet as a Session Border Controller, and also for hiding customer IP
addresses – calls are all routed through one point so that a public ITSP
address can be used for accessing the customers, rather than the customer’s
own IP address.
If required, enter this field with the outbound proxy IP address or domain name
as provided.
