+
+This software **must not be used** to further the Apartheid policies of Israel. Use, modification, or distribution **inside** Israel and the Occupied Territories is strictly forbidden until the demands of the Boycott, Divestment and Sanctions movement have been met:
+
+* Israel has ended the occupation and colonization of all Arab lands occupied in 1967 and dismantled the Wall;
+* Arab-Palestinian citizens of Israel have been granted full equality; and
+* Palestinian refugees have obtained the right to return to their homes and properties as stipulated in UN Resolution 194.
+
+For all other geographic regions **outside** of Israel and the Occupied Territories, use, modification, and distribution are permitted under the terms of the **BSD 3-Clause "New" or "Revised" License** above (Section 1), provided that any future use, modification, or distribution carries the above BDS restriction and abides by the ShareAlike and NonCommercial principles.
+
+This restriction is **not** intended to limit the rights of Israelis or any other people residing outside of Israel and the Occupied Territories.
+
+In any instance where the BSD 3-Clause License conflicts with the above restriction, the above restriction shall be interpreted as superior, and all other non-conflicting provisions of the BSD 3-Clause license shall remain in effect.

+
+> ⚠️ **License Update (May 18, 2025)**  
+> This project is now dual-licensed under the BSD 3-Clause “New” or “Revised” License **and** the additional BDS BY-NC-SA restriction (see [LICENSE](https://github.com/sipsorcery-org/sipsorcery?tab=License-1-ov-file#section-2) § 2).  
+>
+> **Key points of the BDS restriction:**  
+> - **No use inside Israel or the Occupied Territories** until the 1967 occupation ends, equality for Arab-Palestinians is enshrined, and the right of return for Palestinian refugees is honored.  
+> - **Everywhere else**, the BSD 3-Clause terms apply, provided that any redistribution retains this BDS restriction and complies with Attribution-NonCommercial-ShareAlike.  
+> - In case of conflict, the BDS terms in Section 2 take precedence over Section 1.
