Part 2 - Enterprise Requirements & Solutions

Customer Background：

The company’s office area is in the urban area and the factory is in the suburban area, with interconnected internal networks between the two locations.
The existing Cisco telephone system has been decommissioned, but the company intends to reuse 200 Cisco 7965 IP phones and some analog phones.

Requirement 1：The enterprise aims to deploy a feature-rich IP telephone system that supports future expansion and is compatible with other phone brands.

Equiinet Solution：Deployment of the SINA IoT Communication System

（1）Rich Features：Includes call transfer, call forwarding, three-way conferencing, call recording, call logs, and other practical functions to meet diverse daily office communication needs.

（2）Easy Expansion：With a lightweight architecture, the system can be expanded to 1,000 extensions without changing hardware, supporting future phase II and III projects.

（3）Strong Compatibility：Seamlessly integrates with any IP phone supporting the SIP protocol, regardless of brand.

Requirement 2：Reuse 200 existing Cisco 7965 phones on the SINA system to save costs.

Equiinet Solution：By importing and configuring specific files into the Cisco 7965 phones (which cannot be directly registered to the SINA system by default), the team successfully enabled reuse.

All functions—including caller ID, call making/receiving, call transfer, conferencing, and call logs—perform identically to the previous experience.

Requirement 3：Integrate on-site analog phones into the SINA system to maintain the original user experience.

Equiinet Solution：Deployment of FXS Gateways at the Factory

（1）Network Connection：One end of the FXS gateway connects to the network switch and registers to the SINA system via the SIP protocol.
（2）Analog Phone Integration：The other end connects to the existing factory distribution frame (linked to analog phones via multi-pair cables), supporting both RJ45 and RJ21 interfaces for flexible deployment.
（3）Functionality：All analog phones can make and receive calls normally after integration.

Requirement 4：Integrate a 30B+D trunk line into the SINA system and control outbound permissions for specific extensions (e.g., restricting external calls).

Equiinet Solution：

（1）Hardware Deployment：Deploy an E1 gateway in the equipment room, connecting it to the SINA system via IP trunking to enable the 30B+D line.

（2）Permission Configuration：Set up call routes and assign outbound permissions in the SINA system. Restricted extensions can only make internal calls, meeting the enterprise’s management needs.

Part 4 - Solution Highlights

（1）Rich Functions & Expansion Advantages：Covers comprehensive communication features for daily use. Supports free inter-branch communication in future expansions, reducing costs for long-term development.

（2）Strong Compatibility & Cost Savings：Enables reuse of Cisco IP phones and analog phones through configuration adjustments or FXS gateways, significantly cutting equipment costs.
（3）Flexible E1 Gateway Application：Supports 30B+D line integration and offers customized configurations (e.g., direct lines, round-robin lines) to meet diverse communication requirements.
