Configuring SIP Entities

Perform the following for each SIP Interface, Proxy Set, or IP Profile:

SIP Interfaces: To enforce only SIP over TLS, configure only the TLS port and change all other SIP ports (UDP, TCP and SCTP) to 0.
Proxy Sets: When adding a Proxy Address for a Proxy Set, select TLS for the required transport type.
IP Profiles: When adding an IP Profile, configure the 'SBC Media Security Mode' parameter to SRTP.
