No one ever responded to this inquiry but I figured out what the issue
was. I thought I would respond with the solution just in case someone
runs into the same issue in the future.
Firstly, when setting up trunking between servers the "username =" field
is not optional. :) Also, I had a lot of extra fields in place that I
didn't need but hadn't taken the time to remove. I have developed the
opinion that config files should be kept as lean as possible. Here is
the revised SIP peer configuration from sip.conf:
[trunk]
type = friend
username = trunk
callerid =
context = default
host = 172.21.235.1
secret = password
canreinvite = no
disallow = all
allow = gsm

I've got an issue where I am trying to route calls between Asterisk
Servers. I can route calls inbound to a server but seem to have an
authentication issue going out over the same sip account. It appears
that my server isn't sending the second invite after proxy
authentication request. I can't figure out why; any ideas would be
greatly appreciated. Thanks!
