The&nbsp;<strong>SIP protocol<\/strong>&nbsp;(Session Initiation Protocol), as an internationally recognized VoIP signalling standard, enables seamless interconnection between different brands and devices. FARHD SIP video intercom systems can directly connect with mainstream IP PBX platforms (e.g., Asterisk, 3CX, FreeSWITCH), unified communication systems,&nbsp;<strong>Zugangskontrolle<\/strong>&nbsp;units, and property management software \u2013 without additional gateways, significantly reducing integration costs and deployment time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"core-advantages-of-the-farhd-sip-system\">Core Advantages of the FARHD SIP System<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"1-full-scenario-product-portfolio-to-meet-all-your-needs\">1.

The community has 12 buildings, each equipped with a SIP outdoor station, while residents use 7\u201d touchscreen indoor monitors. The system is integrated with the property\u2019s cloud platform, supporting call forwarding to residents\u2019 mobile phones and elevator floor access control. The property management team can manage tenant information and view access logs in bulk through the backend. The system has been running stably for two years, with a 30% increase in resident satisfaction.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"case-2-global-corporate-headquarters-customised-office-access\">Case 2: Global Corporate Headquarters \u2013 Customised Office Access<\/h3>\n\n\n\n<p>A global technology company needed to integrate access control, attendance, and visitor reservation systems. FARHD developed a custom SIP intercom system: outdoor stations work with employee RFID badges, visitors can call the front desk via a reservation code, and the front desk can transfer the call directly to the employee. All call recordings are stored on the company\u2019s internal server to meet compliance requirements. The system also provides APIs to synchronise with the HR system, automatically granting or revoking access rights when employees join or leave.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"frequently-asked-questions-faq\">H\u00e4ufig gestellte Fragen (FAQ)<\/h2>\n\n\n\n<p><strong>Q: Does the FARHD SIP system support PoE power supply?<\/strong><br>A: Yes.
