IAX2 problem: "register_verify: No registration for peer"

Hi,

My Asterisk Version is 1.8.1.1 and I am using the following configuration:

Server 1 (IP Address: 10.0.0.68), iax.conf

[general]
bandwidth=low
jitterbuffer=no
forcejitterbuffer=no
autokill=yes

[COMPANY]
context=from-internal
qualify=yes
type=peer
username=2000
secret=13579abc
host=10.0.0.69

[2000]
type=user
username=2000
secret=9999
host=dynamic
context=from-internal

Server 2 (IP Address: 10.0.0.69), iax.conf

[general]
bandwidth=low
jitterbuffer=no
forcejitterbuffer=no
autokill=yes

register => 2000:9999@10.0.0.68

[COMPANY]
context=from-internal
qualify=yes
type=peer
username=2000
secret=13579abc
host=10.0.0.68

But I get the following error on Server 1:

And the following error on Server 2:

What am I doing wrong? I tried a guest account as well (means: leaving out username and secret), but It didn’t work either.

Thank you,
Christopher
