OIP TAPI Service Provider 8.3

OIP TAPI Service Provider is a Windows telephony driver from Aastra Telecom Schweiz AG that links Microsoft TAPI‑compatible applications to Aastra communication platforms via the Open Interfaces Platform (OIP). It exposes telephone extensions as TAPI lines, enabling computer‑telephony integration such as click‑to‑dial, screen‑pop on incoming calls, and centralized call control from desktop software.

Key capabilities include:

• Call control: make, answer, hold/retrieve, transfer, conference, and hang up
• Real‑time call state and caller/called number notifications for logging and screen‑pop workflows
• Support for single or multi‑line users (e.g., attendant or team scenarios)
• IP‑based connectivity to the OIP server for centralized, manageable deployment

Typical uses include integrating dialing and call handling into CRM/ERP systems, help desk tools, and productivity apps that use TAPI on Windows.

Notes:

• Designed for Aastra platforms that provide OIP; licensing and exact feature sets depend on system configuration and software versions.
• Aastra is now part of Mitel, and product naming may vary by release.
