# Whitelist Zero Touch Provisioning Services for Obihai and Poly Devices

## Objective

Whitelisting ZTP services for Obihai and Poly devices.

## Applies To

- Obihai ATA Adapters
- Poly Phones firmware 5.8+

## Procedure

> [!NOTE]
> Note:

> This list of subnets is not owned or maintained by 8x8, and is subject to change without notice. Links are provided at the bottom of this document to the Source documentation from Poly.

1. Add the PDMS, formerly Obitalk, IPs, and Ports, to the firewall whitelist.
2. If your firewall requires it, whitelist trusted hosts from the second table below.

### PDMS-SP Trusted IP Addresses

| Trusted IP Address | UDP/TCP | TLS |
| --- | --- | --- |
| 54.241.160.4 (Root node server) | 10000 to 20000 TCP: 6800 | 443 |
| 13.52.69.0 | 10000 to 20000 | 443 |
| 13.56.185.145 | 10000 to 20000 | 443 |

### PDMS-SP Provisioning Trusted Hosts

| Trusted Host | IP Address | Protocol(s) | UCS | Description |
| --- | --- | --- | --- | --- |
| www.obitalk.com | 52.9.172.78 | HTTP HTTPS | N | Essential functions for cloud troubleshooting and general connectivity features, including capturing remote syslogs and PCAPs. |
| www1.obitalk.com | 54.183.147.237 | HTTP HTTPS | Y | Essential functions for cloud troubleshooting and general connectivity features, including capturing remote syslogs and PCAPs. |
| pgs.obitalk.com | 54.67.27.166 | HTTPS | N | Enables devices to send local configuration data to the host when the administrator of the services checks a device’s local configuration from the PDMS-SP portal. |
| prov.obitalk.com | 54.193.112.156 | HTTP HTTPS | Y | Enables Zero-Touch customization for device onboarding. Also used for upgrading firmware for OBi devices using the ITSP portal **Firmware** drop-down menu. |
| devpfs.obitalk.com | 52.53.103.203 | HTTPS | N | Used for device profiles as part of ZT customization to match the phone ID with the cloud. |
| api.obitalk.com | 52.52.91.236 | HTTP HTTPS | N/A | Enables you to access APIs from your computer or the app that manages PDMS-SP without adding addresses to the allow list on the device’s network. |
| fw.obitalk.com | 54.241.157.146 | HTTP HTTPS | N/A | Enables you to download firmware from the website. This is optional but future-proof. |
| fw.obihai.com | 52.8.107.151 | HTTP | N | Enables you to download firmware from the list in the PDMS-SP ITSP portal. |
| ucsprov.obitalk.com | 13.52.127.178 | HTTPS | Y | Enables you to provision ZT profiles as part of the claim device feature for UCS. |
| services.obitalk.com | 54.241.157.146 | HTTPS | N | Enables the device to send required data to perform PDMS-SP services like Syslog and PCAP. |

### Claim Device Requirements for UCS

PDMS-SP supports claiming UCS-based endpoints. The service still uses Poly ZTP, so you must add the IP addresses to an allow list for the service to function properly.

| ZTP FQDN | IP Address |
| --- | --- |
| ztp.Poly.com | 3.219.214.168 18.235.37.112 |
| ztp.polycom.com (Recommended) | See [Poly-Provided Documentation](https://info.ztp.poly.com/docs/begin/prerequisites). |

## Additional Information

Obihai adapters and Poly phones on 5.8+ firmware must communicate with the PDMS system before they can be provisioned or come online with 8x8 service. These servers are used for ZTP (Zero Touch Provisioning). For more information, see:

- [Poly-provided documentation](https://info.ztp.poly.com/docs/begin/prerequisites).
