"We've sourced SIP intercoms from three different manufacturers. DJSlink is the only one where the firmware actually matched the documentation, and where engineering support answered our technical questions within hours — not days."
"We operate in Zone 1 hazardous environments. The DJSlink ATEX phone line passed our internal safety audit without a single revision request. That's never happened with any supplier before."
"The API documentation was complete, in English, and the SDK worked out of the box. Our platform integration took 2 weeks instead of the 3 months we budgeted. DJSlink is our exclusive hardware OEM partner now."
"Stock is always available, lead times are consistent, and when a product issue arose — it was resolved with a replacement shipment before I even had to follow up. That's the kind of supplier relationship you build a business on."

SIP Platform Compatibility
Verified Platforms & Certification Bodies
