Hi friends

 I have some doubt in connecting my firefly3rd party softphone from windows
machine to asterisk server in linux .

 My asterisk is behind the "Port Restricted NAT". I am using STUN
server to cross the firewall.

 My STUN server is running in Linux machine.

 When my firefly3rd party softphone sends udp packets to asterisk server machine
the STUN server displays message like
"Binding Request Doesn't contain Message Integrity"

Is there anyone faced problem like this.

Give your suggestion regard above issue.


                   Thanks in Advance

regards

This message does not indicate major trouble.
It simply means that the STUN protocol is not using message integrity 
generation/checking
which is a "checksum" method using HMAC hashes.
STUN works ok without it.
