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

[Sonny Rajagopalan]

This question was asked by Chirag on March 4 2015 earlier, but I am
following exactly the same procedure here and I cannot even get my clients
to register on Asterisk.

Here's my PJSIP.conf:

[transport-tcp]
type=transport
protocol=tcp
bind=0.0.0.0:5061
...

[endpoint_internal](!)
type=endpoint
context=from-internal
disallow=all
allow=!all,ulaw
direct_media=no
rtp_symmetric=yes
message_context=text-context

[auth_userpass](!)
type=auth
auth_type=userpass

[aor_dynamic](!)
type=aor
max_contacts=1
remove_existing=yes

;;; Configuration for user 99999999
...

I used basically exactly the same procedure for UDP based registration and
it works just fine.

Any help is appreciated. The specific error I see on the CLI is:
