When creating an external trunk, which of the following protocol(s) can be selected?

TCP, TLS, and UDP are the protocols that can be selected when creating an external trunk. An external trunk is a connection between Genesys Cloud CX and an external telephony provider, such as a carrier or a PBX. The protocol determines how the SIP messages are transported between Genesys Cloud CX and the external provider. UDP is the most common protocol for SIP trunks, but TCP and TLS can also be used for more reliable or secure communication.References: https://help.mypurecloud.com/articles/external-trunk-settings/ https://doc.didww.com/integrations/genesys/index.html
