Routing Gateway Management in VOS3000


Management Routing is very essential for any kind of soft switches. Perfect routing is necessary for passing the call through. This post is about how to add and manage Routing Gateway option in VOS3000 softswitch.


Double-click on “Navigation” go to “Service management” go to “Gateway service” than “Routing gateways”. The spreadsheet item will appear.

Spreadsheet items:
Gateway ID: The unique ID of the device, used for the authentication of dynamic gateways. For static gateways (usually relay gateways), the only requirement is that their IDs do not conflict with one another, it should be unique.

Gateway prefix: When the number being called is not registered in the system, the call will be routed only to gateways which match the prefix specified here. Multiple prefixes can be specified, separated by commas. Different gateways can be designated with the same prefix. When conflict occurs, the gateway will be chosen according to following numbers (the smallest comes first): Priority number, the ratio of the number of current calls to the number of channels, the number of historical calls and the gateway ID.

Prefix mode (for routing gateways only):
Carry through: Shorter prefixes will be tried if the routing gateway matched by this prefix cannot deliver the call.

Terminate: No more prefixes will be tried if the routing gateway matched by this prefix cannot deliver the call.

See the below Example:

  • If the prefix mode of “gw.101-t-err” is set to “Terminate”, the prefixes being tried for the number “90080001” will be “gw.101.-t-err” and “gw.103” in order.
  • If the prefix mode of “gw.101-t-err” is set to “Carry through”, while others remain the same, the prefixes being tried for the number “90080001” will be “gw.101-t-err”, “gw.103”, “gw.102”, and “gw.101-t” in order.


Softswitch: Specify the MBX used by this routing gateway.

Supplement settings of the gateway.


Type of the gateway
Dynamic: Registration is required before use.

Static: No registration is required. These are usually relay gateways (i.e. routing gateways). Static IP addresses and ports can be specified for them.

Media proxy: See the descriptions in “Phone management” than “Supplementary services”.

Encryption key: The encryption key for the encryption of connections between VOS platforms. In this case, an encryption port must be used for signaling, which, by default, is 3720 for H323 and 5070 for SIP.

Signal timeout: The longest time for the call to be stayed in the signaling status. When the timeout is exceeded, the system will switch a gateway if it is in the “Setup” or “Call Proceeding” status, and will hang up the call if it is in the “Alerting” status.

Legal lengths of the caller number: The lengths of the caller numbers allowed to pass through the gateway (e.g. fill in “11, 14” to allow numbers of 11 digits or 14 digits only).

Note: Left blank to allow numbers of all length to pass through, and fill in “0” to allow no numbers to pass through.

Legal length of the called number: The lengths of the called numbers allowed to pass through the gateway.

IP address: See descriptions in the “Supplement settings”

Password: The password used for gateway registration, which is also the password used for Web query.

Memo: Comments on the gateway

Billing account number: The billing account charged when the gateway is called

Billing account name: The name of the billing account

Billing account balance: The balance of the billing account
