[Asterisk-Users] Asterisk running on DMZ (no NAT) PROBLEMS- OPTION message is out of State

[Marco Mouta]

Hello,

Currenly I've ASterik at Home 1.5 running on DMZ. I can register SJphone
there, good audio on 8200 (webmeet me calls) and i also can dial
Zapata extensions.

When I dial sip phone extensions nothing happens if the client that
i'm calling  is registred, if the client has voicemail it goes to
voicemail.


IMPORTANT:
I get this error message on my Check Point Firewall:

"sip reason:Attack Info - Malformed SIP datagram, OPTION message is
out of State"

By the way i've one client that is running all ok, the others all have
this problem.


I hope some one could help me with this.

Best regards,
Marco Mouta
