One of the key specifications of the Yeastar P550 is its ability to support up to 50 users. This makes it well-suited for medium-sized businesses that require a system capable of accommodating a moderate number of employees. With this capacity, businesses can effectively manage their internal and external communication needs.

The system also boasts a maximum concurrent call capacity of 25. This means that up to 25 calls can be active simultaneously, allowing for smooth and uninterrupted communication flow within the organization. This feature is particularly beneficial for businesses with high call volumes or departments that heavily rely on voice communication.

With a maximum of 8 analog ports, the Yeastar P550 provides the flexibility to connect traditional analog devices, such as phones or fax machines, to the system. This enables businesses to seamlessly integrate their existing analog infrastructure into the VoIP environment, facilitating a smooth transition to the new system.

Furthermore, the P550 supports up to 8 BRI ports. BRI, or Basic Rate Interface, is a digital communication standard commonly used in ISDN networks. The inclusion of BRI ports allows businesses to connect digital devices and take advantage of the features and benefits offered by ISDN technologies.

In addition to analog and BRI ports, the Yeastar P550 offers support for up to 4 cellular ports. This allows businesses to integrate cellular networks into their communication setup, providing them with the flexibility to leverage mobile network connectivity for voice calls. This feature is particularly useful in scenarios where reliable internet connectivity may be limited or as a backup solution in case of network outages.

It’s worth noting that the Yeastar P550 does not support E1, T1, or J1 ports, which are digital communication standards used for higher-capacity voice and data transmission. However, the absence of these ports should not hinder the system’s performance for businesses that do not require such high-capacity connections.

Although the Yeastar P550 does not come with an expansion board, it does offer the capability to utilize external storage through USB. This allows businesses to connect USB storage devices to the system, facilitating features like call recording, system backups, and other storage-intensive operations.

Overall, the Yeastar P550 VoIP IP PBX Phone System is a feature-rich solution that provides businesses with the necessary tools to establish efficient and reliable communication networks. With its support for a substantial number of users, concurrent calls, analog and BRI ports, as well as cellular integration, it offers the versatility and scalability required to adapt to the evolving communication needs of businesses.
