hello, I got the same issue. my sip device getting ok from kamailio, but asterisk reply 401.

but.

this is my config: http://pastebin.com/jGCak01E

and I changed regfwd route to

$du = "sip:50.0.0.10:5060;transport=udp";

forward();

and now I see this in logs:

and show me ur conf please.

Hi All,

I'm running into an issue, I'm not sure whether any of you seen this
yourselves and resolved it. Please share some pointers. My network is:

clients <--> Public IP(Kamailio/RTPProxy)10.1.128.11 <--> 10.1.128.34
(Freeswitch)

The 200 OK response from Freeswitch (on the way back from called party to
caller) to Kamailio is shown below. Notice the Contact header URI host part
contains Freeswitch Private IP (10.1.128.34). Kamailio suppose to change
that to Public IP before forwarding the 200 OK (copied below) to Caller in
public domain. But, it's not. As a result, ACK from Caller is not reaching
back to Kamailio.

How did you or anybody out there using Kamailio resolve this problem? If
needed, I can copy/paste my kamailio.cfg.

yours respectfully, Alexander Vasin.
