Problems with inbound calls

I installed and configured asterisk. Outbound and internal calls work without problems. However inbound calls do not get routed to any of the clients. When doing “asterisk -vvvvvr” it just shows “== Using SIP RTP CoS mark 5” when trying to call in.

sip.conf

[general]
bindport=5060
bindaddr = 0.0.0.0

context=internal
register=2110001:aaa@terrasip.net/1234
register=2110002:bbb@terrasip.net/4321

[test1]
type=friend
defaultuser=test1
secret=test
host=dynamic
context=test1e
nat=yes

[test2]
type=friend
defaultuser=test2
secret=test
host=dynamic
context=test2e
nat=yes

[terrasip1]
defaultuser=2110001
fromuser=2110001
type=peer
secret=aaa
host=terrasip.net
context=terrasip1e

[terrasip2]
defaultuser=2110002
fromuser=2110002
type=peer
secret=bbb
host=terrasip.net
context=terrasip2e

extensions.conf

[general]
autofallthrough=yes

[internal]
exten => 1234,1,Dial(SIP/test1)
exten => 4321,1,Dial(SIP/test2)

[test1e]
include => internal
exten => _XXXX.,1,Dial(SIP/${EXTEN}@terrasip1)

[test2e]
include => internal
exten => _XXXX.,1,Dial(SIP/${EXTEN}@terrasip2)

[terrasip1e]
include => internal

[terrasip2e]
include => internal

Any ideas what I am missing? Thank you very much for your support!

Try with allowguest=yes in [general]
