Hi ALL
as a further dig into the media issue no voice between caller and callee and 
found that the in the request packet of invite header the value of via header 
is coming incorrect  ( as in the below packet is coming the local ip address of 
the machine 192.1682.248 instead of 159.200.37.234. 
my machine is behind the fortigate firewall. could you please suggest how to 
set or change the value of via header , is this will be done at firewall level 
or to change the any value in the opensip configuration file. below is sample 
packet 
U 2018/08/03 16:27:25.156824 159.200.37.234:5060 -> 149.355.453.253:5060

  Hi Bogdan-Andrei,Thanks for the response! it motivated me to read more stuffs 
related to opensips.  I followed the steps of installation  steps and type of 
route define in https://www.opensips.org/ but again i am facing problem in my 
first installation of stepup  Earlier the opensip server was behind the NAT - 
Public address on firewall and opensip machine (Centos) having a local address 
(192.168.2.x) , but now the opensips  machine (version 2.2)  directly hosting 
public address without mapping ( Lan cable from fortigate firewall to opensips 
machine with any mapping or port block all ports open)Scenario is If my UAC1 
(zoiper on my  laptop1) , UAC2 (zoiper on my laptop2 ) and Opensip machine are 
in the same network i.e ISP1 i can easily hear the voice / audio between the 
UAC1 and UAC2#) But i change the Network of  UAC1 (zoiper on my  laptop1) , 
UAC2 (zoiper on my laptop2 ) to connect with ISP2  and opensip machine remain 
on ISP1 then i am able to register and call UAC but their is no voice / audio ( 
RTP Media) among the user agent. ( i am 2 ISP network from different provider) 
I the last 1 week i tried all the solution what ever i am able to find online 
but still its does work. could you please suggest how to troubleshoot further. 
additionally is their any repository where i can study more about the route how 
to they work and how to change / Set the the value in header field of the 
request / response.guidance and direction at stage will help me move further
Thanks in advance , i know few are my quires are wired as i just enter in the 
world of opensips

ThanksSanjeev Kr Sharma

  Hi Sanjeev,
 
 As I understand correctly, you end up connecting into your opensips devices 
from different networks - a devices from the private network (same as opensips) 
and another device from the public network.
  But note that bidirectional direct communication between the 2 devices is not 
possible, as the public device cannot send traffic to a private IP/destination.
 Depending on the opensips cfg, the SIP signaling works, as OpenSIPS will act 
as a bridge between the 2 networks. But this is not true for RTP, as RTP goes 
directly between the 2 devices. So, what you need is to use a media relay 
acting a bridge between the 2 networks.
 
 Regards,
  Bogdan-Andrei Iancu

  Hi , 
  i am  new to opensips world and i installed the openSIPS version 2.2 , facing 
issue of media. Setup is my configuration is like  1) UAC request come through 
fortigate firewall on public address ([email protected])  and then passed to 
my opensip machine (centos 7 , opensip version 2.2) having local address ( 
natted with public address)  2) registration of UAC is fine and if UAC are on 
same network lets say one client on my laptop and another on mobile device 
(both on same ISP WIFI) then voice is going through between the UAC but i 
switch the network of the mobile to telco service provider then their is no 
media pass on in between the UA or some time only one UA able to listen the 
other side. 
  i looked online and search lots of stuffs related to this and changed in 
configuration but unable to solve or find what and where i am getting. i tried 
TCP dump for both kinds of call i.e having voice or no voice but unable to 
identify the difference between calls having voice and no voice. 
  Since i am new to this setup and configuration , just stuck due to above 
problem . 
  Please suggest where to look and what could be the possible reason. Currently 
all traffic ( i.e all ports open) being allow from firewall to machine  
  
  Thanks Sanjeev
