Termination Gateways

Termination Gateways are used to call out from phone.systems™ using created SIP accounts or to forward calls to PSTN destinations. A third-party party termination provider must be added and configured under the Gateways tab section.

To access and manage your termination gateways, click Trunks in the sidebar menu and select the Termination Gateways tab.

Step 2: Input the General Settings:

  • Name: a friendly name for this gateway.

  • Gateway Username: Authorization username

  • Gateway Password: Authorization password

  • Host: Gateway IP address or domain

  • Port: Port used on this gateway (if not entered, port 5060 will be used by default)

  • Allowed Codecs: Multiple codecs may be added for call negotiation between the VoIP service provider and the PBX environment. Codec options that may be selected from the dropdown list are:

    • OPUS

    • G722

    • PCMU

    • PCMA

    • G729

    • GSM

    • telephone-event

Note

the codec priority may be arranged by dragging the listed codecs into the required position, with the left-most codec being of the highest priority.

Important

To use DTMF codes for events such as Interactive Menu options or Feature Codes, ensure that the telephone-event codec is included in the Allowed Codecs list.

Step 3: Configure CLI Rules (Optional):

The CLI Rules are used to automatically modify the source and destination numbers sent to the termination gateway, allowing users to add and remove prefixes or completely rewrite the numbers on a per-gateway basis.

  • SRC Rewrite Rule/Result (optional): Modifies the source number that phone.systems™ sends to the provider’s termination gateway.

  • DST Rewrite Rule/Result (optional): Modifies the calling destination number that is sent to the provider’s gateway.

If no changes are required to be made to the numbers when making outbound calls, then the Rule and Result fields should be left blank.

Note

Knowledge in using POSIX Regular Expressions is required in order to use this feature.
