[asterisk-users] Asterisk and Max TNT Passing calls SIP to PRI, not PRI to SIP Authentication Issue

Hi All,

I have a lab setup with two asterisk servers and a MAX TNT in the
middle like this:

asterisk sip >< sip TNT pri >< pri asterisk

The TNT is running 11.0.6 and the asterisk servers are running
1.2.9.1.  I can get calls to pass from asterisk sip to tnt to pri to
asterisk but not the other way. The call from asterisk to pri to tnt
is good, the TNT is passing SIP invite to the SIP Asterisk server. I
have tried many variations of using sip options insecure,
autocreatepeer, permit/deny, host, user, etc.... but can't seem to get
asterisk to accept an unauthenticated call from the TNT using SIP.  I
keep getting SIP/2.0 407 Proxy Authentication Required.  I know others
have done this, but with older Asterisk versions, I'm wondering what
versions of Asterisk are known to work with the MAX TNT and with what
version of the TNT?

I'm confident this is an asterisk issue, with insecure=very, I should
be able to pass calls to asterisk without trying to authenticate it
first.  But this is not happening.

Here is a debug of a call and a snip from my sip.conf:

sip.conf

host=10.10.14.131
insecure=very
dtmfmode=inband
callerid="MaxTNT" <maxtnt>

reinvite=no
canreinvite=no
disallow=all
