- Indentation for HTML template consistent with other templates.
- Style 'repro' like the upstream project does in all small case.
- Better describe the functions of a SIP server and organize the actions
to be done by the user.
- Set the menu weight so that it does not clash with an existing module.
- Name the application 'SIP Server' instead of 'SIP Proxy' as that
better describes the capabilities of the repro and is simpler for
users to understand.
- Since SIP is a generic protocol implemented by various servers, the
firewall service must describe the protocol instead of the
application. This is similar to the way firewalld handles
http/https. This also make the service descriptions more acceptable
by upstream.
- Split unencrypted and encrypted services so that one can enabled
without the other (a possibility with SIP).
- Add 5061/UDP for SIP over DTLS and DCCP.
