[asterisk-users] Asterisk 13.6.0/The simplest TCP configuration does not work

[Sonny Rajagopalan]

I made some progress. The first thing I have realized is that it is my
Twilio configuration in pjsip_wizard.conf that was killing me. I have since
removed that entire file from /etc/asterisk and I am able to make
"from-internal" context calls (i.e., calls that do not leave the VoIP
island).

Here's what I have right now in pjsip_wizard.conf (again, I have removed it
from /etc/asterisk/ because Asterisk won't even work for "from-internal"
calls with the conf in /etc/asterisk)

[twilio-siptrunk]
type = wizard
sends_auth = yes
sends_registrations = no
remote_hosts = silly.pstn.twilio.com
outbound_auth/username = username
outbound_auth/password = sillypassword
endpoint/context = from-external ;;; change later
endpoint/disallow = all ;;; change later
endpoint/allow = ulaw ;;; change later
aor/qualify_frequency = 15

What should I change/add/modify above to make Asterisk and Twilio work with
TCP? Note that I do not have to trigger a use of the twilio sip trunk for
my Asterisk daemon to not work for TCP. If I have the pjsip_wizard in
/etc/asterisk, it does not work for _any_ call, regardless of whether or
not the call should use the Twilio SIP trunk.

(again, the same asterisk configuration on the same machine connected to
the same twilio SIP trunk worked for UDP)

If anyone knows the trick to make pjsip_wizard.conf work with twilio, I
would very much appreciate any insight...

Thanks,
Sonny.
