Create a trunk under BYOC Premises

Genesys Cloud recommends that you rely on the default settings described in this article. However, if after you create a basic external SIP trunk for your BYOC Premises configuration, you find that you need more control based on the SIP requirements from your carrier, see Configure advanced external trunk settings

If you need more information about any of the settings on the Create/Edit External Trunk page, see External trunk settings
