Hi Daniel
Thank you so much for your response. Here is the SIP trace of one of the calls, I am not
sure where the call initiates but you can see at the end of the file in bold
X-Asterisk-HangupCause: No user responding. I am not sure why is it sending this message
though.
The variables are
Extension/Username=XXXXX
Ext_IP= Public IP
Internal_IP= Asterisk/Kamailio internal IP
Sorry for the long file but again I am not sure where the call initiates
This is the part where that call is hung on.

Asunto: Re: [SR-Users] Kamailio Freepbx Integration Dropping Calls
Hello,
can you gran the SIP trace on kamailio server for such case?
You can use ngrep, like:
ngrep -d any -qt -W byline port 5060
and send the output to the mailing list. You can replace any sensitive information (e.g.,
ip address) before sending to mailing list.
The typical call drop after 30-40 secs is when ACK is not routed properly, but we have to
see that in the sip trace.
Cheers,
Daniel

Hello
I have successfully (I believe) implemented Kamailio 4.1.4 integration with Freepbx 5.2.11
taking as a guide Daniel’s tutorial
http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb.
I just did not create the voicemail tables because voice mail is handled by Freepbx. I
installed the system in a separate box for testing and connected to the Freepbx Production
server via IAX trunk.
The system is behind a Cisco Firewall and looks like this
Remote User Internet
Internal network
Cisco 7960 ----DSL router ---|------Internet --------|-----Cisco ASA 5500
FW--------------Kamailio/Freepbx (Same Box)------IAX Trunk----------Freepbx Production
Server --------|------ PSTN
I have configured the FW to allow UDP and TCP traffic from the corresponding IP as well as
tfpt that is needed for the Ciscos to pick up the configuration from the server. I have a
few remotes Cisco 7960 phones that can register remotely in Kamailio as long as the user
is added with kamctl add user password and as long as the extension is created in Freepbx.
The problem that I have is when try to make a call from the remote Ciscos the call is
dropped after 30 or 40 seconds. I can see from the logs that the problem appears to be
that the server is not receiving responses from the phone

Is this something that we can adjust in kamailio or could it be related to the FW
configuration?? Sorry but I am very new to kamailio and sip.
Thanks
Carlos
