If we do:

    sip.call.respond(ic.id, {code: 200, reason: 'OK'})

we get this:

As investigated in #109, the module 100rel is mandatory and so pjsip adds the 'Supported: 100rel' to the reply. So if some test doesn't want to send this, it will be only possible if a Supported header is added. But some test might not want any Supported header in the reply.
