>          Issue Type: Improvement
>      Security Level: None
>          Components: Resources/res_pjsip_session

> A certain carrier interconnect test requires us to reject certain invites containing content that is not currently supported by asterisk
> This patch tries to implement the correct behavior as according to RFC5261
> RFC 5261 says the following
> 8.1.  Background on Content and Disposition Types in SIP
>    The Content-Disposition header field, defined in [RFC2183] and
>    extended by [RFC3261], describes how to handle a SIP message's body
>    or an individual body part.  Examples of disposition types used in
>    SIP in the Content-Disposition header field are 'session' and
>    'render'.
>    [RFC3204] and [RFC3459] define the 'handling' parameter for the
>    Content-Disposition header field.  This parameter describes how a UAS
>    reacts if it receives a message body whose content type or
>    disposition type it does not understand.  If the parameter has the
>    value 'optional', the UAS ignores the message body; if the parameter
>    has the value 'required', the UAS returns a 415 (Unsupported Media
>    Type) response.  The default value for the 'handling' parameter is
>    'required'.  The following is an example of a Content-Disposition
>    header field:
>        Content-Disposition: signal; handling=optional
