    3. Setting the Gateway through IVR VoIP transmits voice data (packet) via the Internet to achieve telecommunications. This means that the telecommunication quality is closely related to the whole network environment. If any one of the telecommunicating parties has insufficient bandwidth or frequent packet loss, the telecommunication quality will be poor.

    Telephony Settings Prefix Number Rules Trunk Dial Out Verify/ Trunk Dial Out Replace: VoIP gateway will check (verify) the dial out prefix from dial out numbers and change (replace) the prefix to transit out through FXO port. For example: If you transit out with 01907123456, the system will trans to 190601 907123456. If you transit out with 008621123456 the system will replace it with 190200 8621123456.
  • Page 26 Anonymous Caller ID (CLIR): When enabled, the caller’s phone set will not display your number. Note: If you register the gateway to a Proxy, you may be unable to make a call. This is due to the fact that the gateway doesn’t send the number for authorization. Anonymous Transit in W/O Caller ID: FXO won’t detect caller ID, and the gateway will dial out with anonymous caller identification.
  • Page 27 Dial-out Prefix: It is the number dialed automatically by the system when the FXO interface diverts a call to the PSTN by VoIP. FXO Line Default Dial-Out: To set the dial-out number when this FXO line is indicated. Example: If PBX extension needs to dial “0” to make a PSTN call, and the FXO are connected to PBX extension.
