# SIP Zones

A SIP zone is a grouping of voice over IP (VoIP) hardware and resources that is used for managing and routing calls. Zoom Contact Center offers customers hosted on Zoom’s United States-based global service cluster (US01) SIP Zone and PSTN connectivity from the following data centers, enabling users to connect to the most suitable data centers based on their location and needs:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><strong>North America</strong></td><td><ul><li>U.S. West, California</li><li>U.S. East, Virginia</li></ul></td></tr><tr><td><strong>Europe</strong></td><td><ul><li>Netherlands, Amsterdam</li><li>Germany, Frankfurt</li></ul></td></tr><tr><td><strong>APAC</strong></td><td><ul><li>Australia, Sydney</li><li>Australia, Melbourne</li><li>Japan, Tokyo</li><li>Japan, Osaka</li><li>Singapore</li></ul></td></tr></tbody></table>

### Regional Support

For customers that require data localization and are located in supported regions, Zoom Contact Center supports region-specific accounts. Customers with a region-specific account are forced to initialize all calls from their region’s associated data center and can't utilize SIP zones outside of their account’s region; however, calls and media may continue to connect internationally if required.

The following list details supported regions and region-specific data center locations available with Zoom Contact Center:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><p><strong>Europe</strong></p><ul><li>Germany, Frankfurt</li><li>Netherlands, Amsterdam</li></ul></td><td></td></tr><tr><td><p><strong>Kingdom of Saudi Arabia</strong></p><ul><li>Jeddah</li><li>Riyadh</li></ul></td><td></td></tr></tbody></table>
