The two sorcery options for pjsip.conf "allow" and "disallow" both accept a list of codecs and set the same table of codecs in behind the scenes. The difference being of course that the disallow field inverts the meaning.</div>

I have a suggested patch (see <a href="https://reviewboard.asterisk.org/r/3193/" target="_blank">https://reviewboard.asterisk.org/r/3193/</a>) to make the disallow option disappear in a fashion. You can still use the disallow option in pjsip.conf, but when viewing the settings with pjsip show endpoint # only the allow list would appear. This is accomplished by marking the disallow field as an alias.</div>
