How to Create and Configure BYOC?

    With Zoho Voice you can create and configure BYOC (Bring Your Own Carrier) setup by connecting your existing telecom carrier to Zoho’s cloud telephony platform using SIP trunks. This setup enables easy call routing without changing your current phone numbers.

    Note

    Only the super admin and admins can create and configure BYOC.

     

    What are the prerequisites to use BYOC solution?

    For Zoho Voice to work with your current carrier, ensure your current carrier:

    • Is SIP compliant

    • Extends support for the TCP, UDP, or TLS trunk transport protocols. Only TCP, UDP, and TLS over IPv4 are supported. IPv6 is not supported.

    • Possesses one or more publicly routable IP addresses or domain names
       

    How to setup BYOC in Zoho Voice?

    Getting Started

    1. Configure and define SIP trunks and IP Access Control List for a new BYOC trunk.

    2. Each BYOC trunk defined is subject to further verification by Zoho Voice. Upon successful approval, the status of the trunk becomes active and enabled to transfer and receive calls.

    3. Upon approval of BYOC trunk, add your existing numbers to the newly approved BYOC trunk. Zoho Voice will verify it via call OTP and approve the numbers.

    4. Configure all the call settings for the numbers added under the Call Config page.

    5. Send and receive calls from your existing carrier utilizing Zoho Voice.

    Below are the detailed steps for creating and configuring a new BYOC trunk in Zoho Voice:


    Creating a BYOC Trunk

    1. Go to Settings and select the BYOC from the left sidebar menu.

    2. On the BYOC homepage, click the Add button.

    3. You'll be taken to the Add BYOC form, where you can add configurations for the new BYOC trunk and define how the calls are handled between Zoho Voice and your current carrier.

    4. Add a suitable name under the Name field to identify the new BYOC trunk.

    5. Mention the SIP Trunk and IP ACL details.


    Defining SIP Trunk

    • Under SIP Trunk section, configure multiple publicly routable Fully Qualified Domain Names(FQDNs) or hostnames or IP addresses belonging to your current carrier, along with their associated priority levels, so that Zoho Voice can use them to send calls.

    • SIP URI field: Add the list of publicly routable SIP domains or hostnames or IP addresses procured from your current carrier.

    • Protocol field: Specify the appropriate trunk transport protocol supported by your current carrier for establishing connections.
       

      Note

      Only UDP, TLS, and TCP over IPv4 are supported. IPv6 is not supported.

    • Priority field: You can assign priority numbers from 1 to 10 to each of your current carrier's SIP domains. Zoho Voice routes the SIP traffic while handling calls based on priority levels, with the lowest number having the highest priority. If the trunk with the highest priority experiences an outage and becomes unavailable, the SIP traffic will be rerouted through the trunk with the next highest priority level.

    • The User Name and Password fields are optional, which lets you configure the credentials to connect to your SIP Trunks in case you need them. 

    • To add multiple entries, hover over an existing entry and click the add(+) icon. Similarly, to delete an entry, click the delete(x) icon.

     

    Defining IP ACL 

    • Under the IP ACL section, define the IP addresses of your current carrier through which the inbound traffics are originated. Only the mentioned IPs are permitted access for inbound traffics.

    • IPv4 and Bitmask field: Add multiple public SIP signaling IP addresses provided by your existing carrier that enables Zoho Voice to verify and allow inbound SIP traffic.

    • You can add multiple entries by clicking the add(+) icon. Similarly, to delete an entry, click the delete(x) icon.

    1. Click Save to save the SIP trunks and IP ACL configurations for the new BYOC trunk. 

      Once saved, you’ll be redirected to the BYOC homepage, where the newly created trunk will be listed along with its current status.


    BYOC Status

    • Config Approval Status displays the approval status from Zoho Voice. Available status - Pending, Approved, Rejected.

    • Trunk PBX Status displays the deployment status of the approved configuration in the Zoho Voice PBX system. Available status - Active, Inactive.

       

      Note

      The Config Approval status of the newly saved BYOC trunk will be displayed as Pending and the Trunk PBX status will be Inactive. This indicates that the trunk is under review by Zoho Voice for verification.

    • You can edit the trunk configuration by clicking the Edit icon. To remove the submitted trunk, click the Delete icon.
       

      Note

      If you edit an already approved trunk (with Config Approval status: Verified and Trunk PBX status: Active), it will be re-submitted for verification by Zoho Voice.
       


    How to add your BYOC Numbers?

    Upon successful approval, the status of the trunk becomes active and is enabled to send and receive calls.

    1. In the BYOC homepage, click the approved BYOC trunk. You will view the Details and Numbers tabs.

    2. Click the Details tab to review and edit the configurations if needed.

    3. Navigate to the Numbers tab to add your numbers (from your current carrier) into Zoho Voice.
       

      Note

      You can only add BYOC numbers and their configurations after the BYOC trunk configurations are successfully verified by Zoho Voice.

    4. To add numbers, click the Add button.

    5. Add your numbers one by one under the Number field.

    6. For each number, attach a valid document as proof of ownership.

       

      Note

      The valid document should be the number purchase invoice from your existing carrier.

    7. To add more numbers, hover over the number field and click the add(+) icon on the right.

    8. Once all the required numbers and supported invoice documents are added, click Save.

    9. Next, verify each number by clicking the Verify OTP button and entering the OTP received via call to the respective number.

      • Each number added to your active BYOC trunk is subjected to further approval by Zoho Voice.

      • Once approved, all inbound and outbound calls will be managed through Zoho Voice.

      • To remove a number from your BYOC trunk, click the delete(x) icon next to it and save your changes.
