Keep analog services active while you modernize the voice core. The AudioCodes LD809-EH provides 8 analog termination/pass-through ports in a PCIe form factor, giving infrastructure teams a clean path to connect legacy endpoints to an IP telephony architecture. It is designed for environments where replacing every analog device is not practical, whether that means fax lines, elevator phones, alarms, or other business-critical endpoints. For organizations managing phased migrations, this type of gateway matters because it preserves continuity. You can maintain service for devices that still depend on analog signaling while consolidating telephony management around SIP and IP infrastructure. The PCIe deployment model also suits systems that need an internal hardware footprint rather than an external appliance. AudioCodes is widely deployed in enterprise voice environments, and this model reflects that focus: straightforward port expansion, legacy compatibility, and a form factor suited to controlled rollout plans. For procurement teams, it offers a targeted way to extend the life of existing analog assets without overbuilding the solution.
