Hi List,

i tcpdump on my kamailio server.

when uac registered with source port 5060 

the uac will remain  Cflag:: 0 and did not have the Received: field.

i also tried some iphone sip apps.

some uac app will register with src port 5060 and some will not.

anyone have solution for this?

or how to prevent uac register with src port 5060 ?

thanks!
