​I'll bet that if you do a "pjsip show transport twilio"​ you won't see any
Identify or Matches.  I think there's a bug in the wizard that's not
correctly handling the "\;transport=tcp" in all cases when it's appended to
remote_hosts.  I'll check on it tomorrow.

​Do this instead:​

remote_hosts = sillyapp.pstn.twilio.com
server_uri_pattern = sip:${REMOTE_HOST}\;transport=TCP
client_uri_pattern = sip:${REMOTE_HOST}\;transport=TCP
contact_pattern = sip:${REMOTE_HOST}\;transport=TCP

Also, make sure that your Twilio "Origination URI" has the ";transport=tcp"
appended.

​I'll be working ​on the wiki tomorrow as well. :)
