Exceptional Connectivity

Highlight of PR08-Pro

1. Protocol Compatibility

With 8 FXS ports and supporting Contact-ID for alarm, V.150.1 for Modem over IP, and T.38, T.37 FAX standards, the PR08-Pro can not only provide 8 SIP lines for users to make regular calls but also give you great flexibility in upgrading lines for alarm system, elevator phone, FAX machines and any other legacy analog terminals that are adapting to multiple scenarios.

2. Network Failover Between Two WAN Ports

PR08-Pro has two WAN ports, WAN1 as the primary connection and WAN2 as the backup connection. PR08-Pro will evaluate the current connection, and if failure is detected it will auto-switch the network port. With aggressive detection rules, you can expect a quick response system that can switch network links within 15 seconds and ensure a highly reliable data connection.

3. Power Backup Function

PR08-Pro has a built-in battery, DC input, and Type-C USB ports. With the internal battery, once the DC power supply is down the PR08-Pro will keep running with the internal battery or power bank seamlessly. Under the 65w power bank or internal battery, any device that's powered by PR08-Pro can work perfectly even under a power outage. Once the DC power supply is back, PR08-Pro will charge the internal battery and power bank under safety speed, ensuring uninterrupted running when facing power failure.

4. Power Cycling and Remote Control

PR08-Pro provides advanced power output capability, you can use less equipment to build an uninterrupted system. WAN PoE out and UPS 4-Pin Molex port giving you flexibility in choosing your component. Under multiple remote-control methods, such as TR069 and SNMP, power cycling is supported to restart equipment to correct frozen, suspended, or malfunctioning equipment.

5. Working with 3rd Party Router

PR08-Pro supports two WAN ports. We could connect two LTE routers to WAN ports or just connect one external LTE router as a wireless backup. It is flexible to select an LTE modem, e.g., LM150 or 5G CPE T5300, as an external link. You could also combine it with a third-party router with PR08-Pro. It is unique equipment in the market that supports full VoIP functionality ATA with a built-in battery.

Scenario for POTS Replacement

The PR08-Pro solves the problem of protocol compatible with VoIP when connected to legacy analog equipment like elevator emergency call panels, fire and burglar alarm panels, FAX machines, ATMs and POS terminals, and so on. With a built-in battery and external power bank, it could last over 24 hours of power backup during a power outage.

Vola POTS Media SBC is a cloud-based Session Border Controller which is dedicated for POTS replacement service. Compared to PSTN, IP network is relatively unstable. Due to the complex of modern network, Jitter, lag and packet loss happens from time to time. Vola SBC is deployed based on AWS (Amazon Web Services), the stability of the route from SBC to your PBX server is maximized by utilizing the cloud-to-cloud connection. There will be less network unit between two joints, and such route is guaranteed under high standard. It is providing a way to transmit POTS Media stably under unpredictable Network.

PR08-Pro combined with POTS Media SBC to form a POTS Replacement solution, Vola is bridging the gap between traditional telephony and cloud-based communication services, it is an ideal choice for businesses transitioning to Unified Communications as a Service (UCaaS), enabling them to retain the functionality of their analog devices while leveraging the scalability and efficiency of cloud platforms.
