Rear one,
I installed server Asterisk on my root.
Only I do not come simply with X-Lite drauf. I always get the error 408

On my Home server with the same conf runs it without problems.

What can I make?

My confs:
Code:

extensions.conf
[default] 
exten => 1,1, dial (SIP/1,20)
 exten => 1,2, VoiceMail (1, u)

 exten => 2,1, dial (SIP/2,20)
 exten => 2,2, VoiceMail (2, u)

 exten => 9,1, VoiceMailMain ($ {CALLERID (num)}, s)

sip.conf
[general] 
port=5060 
bindaddr= 0.0.0.0 

[1] 
type=friend 
secret=1234 
host=dynamic

 [2] 
type=friend 
secret=1234 
host=dynamic

I could eingrenssen the problem.

My server has two IP's. But only one can in the correct network.
Asterisk tries to go however over these IP.

that spends with ngrep:
Code:

OK ONE. I also solved the problem.

Next problem.
it tries to answer to my Netwzerk IP and not to my Internet IP.

For what do I have to change thereby my Internet IP take?
