On a per trunk group basis, the METHODS parameter disables SBC support for particular SIP messages. For SIP calls in some environments, the following SIP messages are not recognized and supported. This facility allows you to similarly disable support for these messages in the SIP software. When support for one of these SIP message types is disabled, the message is rejected with a 405 code.
