In today’s environment, where enterprises prioritise data security by keeping information within their own network, premises, and infrastructure under the control of their own employees, it is unrealistic to expect real security from third-party cloud telephony providers—especially when complete call recordings and sensitive call data reside on external servers managed by unknown personnel. While cloud telephony is marketed as a convenient, zero-investment solution, choosing it as the primary communication platform is increasingly a penny-wise, pound-foolish decision. The perceived cost savings are largely an illusion, as the recurring monthly OPEX rarely justifies the avoided CAPEX over time. Much of this shift toward cloud telephony stems from customer unawareness of alternatives that offer far better convenience, significantly higher security, and only marginal CAPEX and OPEX, delivering true long-term value without compromising data control.

| CLOUD TELEPHONY your call data, call logs, and recordings to external/insecure environments, creating significant data-security risks. | |
| CLOUD TELEPHONY also fails to deliver true Caller Line Identification (CLI): incoming calls show only the provider’s CLI—not the customer’s—leaving employees unaware of the caller’s importance. | |
| In CLOUD TELEPHONY even Outgoing calls go with inconsistent provider CLIs, often multiple numbers, creating poor brand image and reducing customer confidence. | |
| In contrast, a Com1 Cloud IP PBX keeps all call data and recordings securely on your own server while giving you full cloud-telephony-like convenience with your own telecom resources and consistent CLI. |
At Com1, Service First isn’t a slogan—it’s our culture. While others portray IPPBX as rocket science, we simplify it and make our dealers and customers true partners. From open & universally available hardware to ISO-based installations to unlimited license transfers and unlimited reinstallations, we empower them to remain fully independent even during critical failures. Our open ticketing system and comprehensive help menu for every button and screen reinforce our commitment to keeping support costs low by making you active partners & delivering a cost-effective support model that disrupts traditional industry practices.
Com1 runs on standard, globally available computer hardware—motherboards, RAM, HDD/SSD and SMPS—that can be sourced and serviced locally, eliminating dependence on the manufacturer during critical situations. While some competitors lure customers with sleek proprietary boxes that lock them into controlled service and costly, delayed replacements, Com1 gives complete freedom: in the event of hardware failure, the customer or dealer can simply replace the faulty component locally and restore the system instantly using our cloud restore or reinstate options, handling even the worst failures in under two hours.
Com1 offers unlimited reinstallation and license transfer, enabling customers and dealers to handle even major hardware issues with ease—unmatched by any other system in the world. Instead of struggling with complex repairs, they can back up the voice files, database, and voice prompts, fix or replace the hardware, and then reinstall the system in about 20 minutes. Restoring the database, voice files, and voice prompts brings the system back exactly to where it left off. The entire process can be completed in about two hours, putting the system back online with minimal downtime.
After the new licensing regime began, transferring PBX licenses between CPUs became a major pain point—manufacturers took 7 to 30 days to validate transfers, causing serious downtime risks. Keeping a duplicate licensed CPU as standby was impossible and expensive, leaving both dealers and customers helpless during failures. With Com1, dealers can instantly transfer and activate licenses on new hardware without our intervention, ensuring zero downtime and making the entire process fast, seamless, and stress-free for everyone.
Restoring a failed IPPBX has always been a dealer’s nightmare, as it requires redoing hours—or even days—of programming, settings, and fine-tuning. With Com1, the system automatically backs up configuration files to our secure cloud server every time there is a change in programming, allowing the dealer to restore any of the latest backups in under a minute, without keeping hard copies or manual files. This restore capability works subject to the customer’s network policies, and whitelisting our cloud server IP is required..
If a customer’s network policies do not allow file transfers to our cloud server—our preferred backup method—Com1 offers a local backup alternative. The server automatically stores all databases, not just configuration files, onto a pen drive (included with Com1 hardware or supplied by the customer for their own hardware). In case of a failure, the customer or dealer can reinstall and fully restore the system to the previous night’s backup point, with any potential data loss limited only to the changes made between the last midnight and the time of failure.
Com1 automatically backs up all voice prompt and IVR audio files to our secure cloud server as they are created or updated. In most cases, when a failure occurs, neither the dealer nor the customer knows where the original audio files were stored, making recreation tedious and time-consuming. With Com1, you can simply download the required files instantly and restore them in no time, ensuring seamless continuity with zero hassle.This restore downloading works subject to the customer’s network policies, and whitelisting our cloud server IP is required..
As part of our Service First design, Com1 offers a simple yet powerful Terminal Health Check feature. By dialing *65, the system automatically announces the extension number, prompts the user to speak and then plays back the recording to verify both microphone and speaker functionality. It also triggers an incoming ring to confirm the ringer is working. With this single test, customers or service engineers can quickly validate the complete health of any terminal device.
Being a software product operating on a network and with ever-increasing online threats from unethical hackers, it is crucial to keep the system regularly updated. Com1 undergoes continuous feature enhancements and security updates, and we strongly recommend customers stay current using our simple one-click update, which can be initiated by either the customer or the dealer. The update completes in under two minutes and automatically generates an audit trail, making the entire process effortless, secure, and fully transparent.
The backbone of our support ecosystem is our fully transparent ticketing system. Com1 minimizes support needs through a reliable product, well-trained partners, intuitive self-help tools, and detailed on-screen help. When required, dealers can log tickets directly in our portal, with a typical turnaround of 1u20133 hours, depending on the issue. Every ticket—from day one of installation—is fully visible: customers can view them in the GUI, and dealers through the portal. This end-to-end visibility ensures complete transparency and accountability at every stage.
Com1 offers detailed help for every menu / popup / screen in simple, easy-to-understand language—making it one of the most thoroughly documented IPPBX systems in the industry. This stands in complete contrast to the common industry practice of keeping information opaque and creating artificial complexity to boost service revenue. In addition, our built-in AI assistant provides comprehensive answers to any query—simple or complex—even when it involves multiple menus, options, or configurations. This intelligent support system greatly reduces effort for both dealers and customers, making it the shining jewel in Com1 Service First crown.
As an IP-based system, Com1 often integrates with multiple endpoints, devices, and external equipment, making IP-level troubleshooting essential. Instead of opening command prompts and manually typing ping commands for each IP, Com1 provides a built-in Ping utility right next to every configured IP address in the GUI. With a single click, service personnel can instantly view ping results without navigating to any separate screen. Though simple, this feature is a game-changing, dealer-appreciated tool that makes troubleshooting seamless—especially during critical situations.
Configuring an IPPBX can be cumbersome, especially in large installations involving bulk extensions, ringing plans, directories, and other mass entries. While the GUI is user-friendly, nothing matches the speed and comfort of working in Excel. Recognizing this, Com1 provides an Excel import utility on every screen where bulk programming is needed. Dealers can export existing data, modify or add entries in the same format, and simply import it back for instant updates. Even if mistakes occur, the system can be restored to the previous state in seconds—making bulk configuration fast, safe, and exceptionally convenient.
