Configure advanced SIP phone trunk settings

AI-generated summary

Genesys Cloud provides advanced SIP phone trunk configuration options beyond default settings for users requiring greater control over their telephony infrastructure. The configuration interface is organized into seven functional sections: General (call settings, maximum call configuration, trunk language), Transport (network options, retryable reason/cause codes, Far-End NAT Traversal), Media (audio handling and preferred codec lists), Authentication (digest authentication), Provisioning (HTTP/HTTPS settings), Diagnostic (media capture, protocol capture, phone system logging for troubleshooting call quality issues), and Custom (for Genesys Cloud Technical Support personnel to modify configurations for troubleshooting). Access to these settings requires Telephony > Plugin > All permissions. While Genesys Cloud recommends relying on default SIP phone trunk settings, this documentation enables administrators to adjust basic settings and Connection Configuration parameters through the Create/Edit Phone Trunk page. The Diagnostic section is specifically designed to collect traffic information when working with Genesys Cloud Technical Support, and the Custom section should only be modified under direct guidance from support personnel.

Genesys Cloud recommends that you rely on the default SIP phone trunk settings described in the Create a SIP phone trunk article. However, if you need to exercise more control over the configuration of your SIP phone trunk, investigate the information presented in this article. Here you’ll find links to information on adjusting the basic settings as well as the configuring the settings found in the Connection Configuration section of the Create/Edit Phone Trunk page.

If you have questions or need more information about any of the settings on the Create/Edit Phone Trunk page, see the SIP phone trunk settings reference.
