Hi ,

I also have a doubt like whether rtpproxy is mandate for NAT traversal.
Without that RTP between two sip clients.. Is it not possible here ?
Kindly clarify.. since i am new to this kamailio ims.

Thanks

Also check the SDPs and make sure you get the internal up of rtpproxy on the internal side, and the external on the external side.

Can you explain some more when you mean by "RTP alone is not coming."? And, how are you checking/verifying that?

Hi ,

Yes I have configured as you mentioned only . In my pcscf only i have rtpproxy also configured. 
Floating IP i have given in listen address also as
listen = 10.40.10.3:4060 advertise 10.45.4.22:4060

10.40.10.3 - private ip
10.45.4.22 - floating ip
Still RTP alone is not coming.

Is it the only way of configuring NAT ?

Thanks.

Hello Pavithra,

Have you tried advertising the floating IP of the VM running RTPProxy as follows?

Edit /etc/default/rtpproxy file as follows:

# Additional options that are passed to the daemon.
EXTRA_OPTS="-l 172.24.15.30 -d DBUG:LOG_LOCAL0"

here, "-l <PUBLIC_IP>"

Hope it helps.

Supreeth

Hi ,

Could anybody please give me the approach how to configure NAT in kamailio IMS.

I have installed kamailio IMS in openstack environment which has private ips for all four vms (each component in one vm). pcscf has one floating IP attached. I have enabled "WITH_NAT" and configured rtpproxy .

when i make a call from outside of openstack using 2 zoiper clients with outbound proxy keeping floating ip of pcscf, I am getting 200 ok with all SIP packets correctly flowing but there is no RTP Packet.

When i try the same within openstack environment without using public ip, I am getting RTP Packets.

Kindly tell me the procedure of NAT Enablement or do i need to do anything other than this.

Kindly help because i am stuck with this for long time.


Thanks.
