Hi All,
I have set up Kamailio in the following manner:
Kamailio (Physical Server: Register to Telecom Operator Carrier SIP trunk)
---> Asterisk Server (on Cloud having public IP)
I am successfully able to route the call to Asterisk server on Cloud when I
make a call to the number provided by the carrier and there is audio also
on both sides.
However, when I am making an outbound call from Asterisk server to the
number through Kamailio, there is no audio when I pick up the call. I have
tried to capture the traces but not able to understand the exact problem
here.
Note: I am running the RTP proxy on Kamailio server.
Any help on why this might be happening?
Thanks.
Regards

SDP is probably wrong, a trace here would help.

Is the telecom operator on a private network? The 200 OK SDP is asking the
telco to send the rtp to 10.0.X.X.
The 200 OK (Kamailio->telco) the sdp says:
c=IN IP4 10.0.X.X
That should be an IP the telco can reach.
You need to configure kamailio and RTPProxy to set an IP the telco can
actually reach. And probably do it on both the INVITE and the 200 OK.
On the initial invite, you should do the the same.

Yes, the telecom operator is on the private network. 10.0.X.X is the SBC IP
of the telecom operator to which we register. 10.0.X.X is reachable only
through the second network interface. The complete flow is given below:

Here 3.236.72.101 is Asterisk Server, 192.168.0.192 is local first network
interface IP, 10.0.87.230 is second network interface IP and 10.0.76.9 is
telecom operator SBC IP to which we do SIP register.
We are running the rtpproxy on local IP (192.168.0.192) in the following
way:
*rtpproxy -F -p /var/run/rtpproxy.pid -u asterisk -l 192.168.0.192 -s

So let me get this right:
asterisk (10.0.x.x)--->(192.168.0.192) proxy (10.0.x.x)--->(10.0.x.x)telco
op
There's something i'm not seeing.
Can you explain further like i did above?

Hi All,
I have set up Kamailio in the following manner:
Kamailio (Physical Server: Register to Telecom Operator Carrier SIP
trunk) ---> Asterisk Server (on Cloud having public IP)
I am successfully able to route the call to Asterisk server on Cloud
when I make a call to the number provided by the carrier and there is audio
also on both sides.
However, when I am making an outbound call from Asterisk server to the
number through Kamailio, there is no audio when I pick up the call. I have
tried to capture the traces but not able to understand the exact problem
here.
Note: I am running the RTP proxy on Kamailio server.
Any help on why this might be happening?

Hello,
Could you share your Asterisk's sip context where you set up connectivity
with telco? Just delete all usernames and passwords, if any....
Your setup is very similar to the one I have with a very large telco in my
country, and it works fine as long as you always keep Asterisk on the RTP
path (no re-invites allowed, NAT always active)

Hi All,
I have set up Kamailio in the following manner:
Kamailio (Physical Server: Register to Telecom Operator Carrier SIP
trunk) ---> Asterisk Server (on Cloud having public IP)
I am successfully able to route the call to Asterisk server on Cloud
when I make a call to the number provided by the carrier and there is audio
also on both sides.
However, when I am making an outbound call from Asterisk server to the
number through Kamailio, there is no audio when I pick up the call. I have
tried to capture the traces but not able to understand the exact problem
here.
Note: I am running the RTP proxy on Kamailio server.
Any help on why this might be happening?
Thanks.

This is how it looks:
- Asterisk is running on Cloud having a public IP (3.236.X.X)
- Kamailio is running on a Physical server having 2 NIC ports.
- One of them is connected to the SIP trunk and this NIC port local
IP is 10.0.87.X. We register to the SBC server (10.0.76.X) of telecom
operator carrier through this port.
- Second NIC port is connected to ILL for internet connection having
local IP as 192.168.0.192 and public IP as 14.X.X.X
- To make an outbound call, Asterisk Server (3.236.X.X) sends the call
to Kamailio server on public IP (14.X.X.X) and in turn Kamailio server
sends the call to telecom operator SBC (10.0.76.X) through 10.0.87.X port.
Here is the actual flow:
(Asterisk)
(Kamailio Local ILL Port) (Kamailio Local SIP
Interface) (Telecom Operator SBC)

Since your asterisk server is in the cloud, make sure the relevant udp audio port range is
open to the telecoms carrier.
It is possible that your firewall/security group setup allows an incoming reply on a port
when something first goes out on that port which can explain why audio works in one
direction but not the other.

This is how it looks:
Asterisk is running on Cloud having a public IP (3.236.X.X)
Kamailio is running on a Physical server having 2 NIC ports.
One of them is connected to the SIP trunk and this NIC port local IP is 10.0.87.X. We
register to the SBC server (10.0.76.X) of telecom operator carrier through this port.
Second NIC port is connected to ILL for internet connection having local IP as
192.168.0.192 and public IP as 14.X.X.X
To make an outbound call, Asterisk Server (3.236.X.X) sends the call to Kamailio server
on public IP (14.X.X.X) and in turn Kamailio server sends the call to telecom operator SBC
(10.0.76.X) through 10.0.87.X port.

Hi All,
I have set up Kamailio in the following manner:
Kamailio (Physical Server: Register to Telecom Operator Carrier SIP trunk) --->
Asterisk Server (on Cloud having public IP)
I am successfully able to route the call to Asterisk server on Cloud when I make a call
to the number provided by the carrier and there is audio also on both sides.
However, when I am making an outbound call from Asterisk server to the number through
Kamailio, there is no audio when I pick up the call. I have tried to capture the traces
but not able to understand the exact problem here.
Note: I am running the RTP proxy on Kamailio server.
Any help on why this might be happening?
Thanks.

You need to also
INVITE
Asterisk->kamailio offer the asterisk’s public IP in the SDP.
Kamailio->telco offer in the invite the rtpproxy’s prívate IP (10.x.x.x)
And on the 200
Kamailio->asterisk offer the rtpproxy’s PUBLIC ip.
On the cloud firewall, you need to allow the rtpproxy and Kamailio’s public
IPs.
On the asterisk, you need to configure its public IP as the SDP, not the
private.
You also need to start rtpproxy in bridge mode providing both the public
and private IPs at start (or config)
Hope this helps.

Yes, the telecom operator is on the private

Hi Daniel,
Sorry it took some time for me to make these changes.
I have made all the changes as suggested by you however it still doesn't
seem to work. No audio in the outbound call however incoming call works
fine.
Here are the SIP traces after making the changes:

On the cloud Asterisk, all the relevant public IPs are already allowed.
Have run the rtpproxy on the bridge mode with the following command:
*/usr/local/bin/rtpproxy -s udp:127.0.0.1:7722 <http://127.0.0.1:7722> -u
asterisk -p /var/run/rtpproxy/rtpproxy.pid -l 192.168.0.192/10.0.87.230
<http://192.168.0.192/10.0.87.230>*
Apart from this, in the Asterisk console I can see that the RTP packets are
being sent to Kamailio
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022310, ts
029280, len 000160)
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022311, ts
029440, len 000160)
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022312, ts
029600, len 000160)
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022313, ts
029760, len 000160)
However, there isn't any log for receiving the RTP packets unlike for
incoming calls
Anything am I missing here?
Thanks.

On the cloud Asterisk, all the relevant public IPs are already allowed.
Have run the rtpproxy on the bridge mode with the following command:
*/usr/local/bin/rtpproxy -s udp:127.0.0.1:7722 <http://127.0.0.1:7722> -u
asterisk -p /var/run/rtpproxy/rtpproxy.pid -l 192.168.0.192/10.0.87.230
<http://192.168.0.192/10.0.87.230>*
Apart from this, in the Asterisk console I can see that the RTP packets
are being sent to Kamailio
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022310, ts 029280, len 000160)
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022311, ts 029440, len 000160)
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022312, ts 029600, len 000160)
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022313, ts 029760, len 000160)
However, there isn't any log for receiving the RTP packets unlike for
incoming calls
Anything am I missing here?
Thanks.

Kashish,
Best you can do is take a trace on BOTH ends and share it with us.

Hi Daniel,
Sorry it took some time for me to make these changes.
I have made all the changes as suggested by you however it still doesn't
seem to work. No audio in the outbound call however incoming call works
fine.
Here are the SIP traces after making the changes:

On the cloud Asterisk, all the relevant public IPs are already allowed.
Have run the rtpproxy on the bridge mode with the following command:
*/usr/local/bin/rtpproxy -s udp:127.0.0.1:7722 <http://127.0.0.1:7722> -u
asterisk -p /var/run/rtpproxy/rtpproxy.pid -l 192.168.0.192/10.0.87.230
<http://192.168.0.192/10.0.87.230>*
Apart from this, in the Asterisk console I can see that the RTP packets
are being sent to Kamailio
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022310, ts 029280, len 000160)
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022311, ts 029440, len 000160)
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022312, ts 029600, len 000160)
Sent RTP packet to 14.98.22.110:11648 (type 08, seq 022313, ts 029760, len 000160)
However, there isn't any log for receiving the RTP packets unlike for
incoming calls
Anything am I missing here?
Thanks.

It’s very difficult to read, don’t paste an sngrep screenshot. If you can,
please save the call to a file, then share that.
