rtpproxy : only one NIC interface #10

Open yboujraf opened 3 years ago

yboujraf commented 3 years ago

Dear @davidcsi

I am still using RTPPROXY.

I have only one NIC interface on my server with an private ip address and using nat 1:1

I am confused about :

What that means the public & private ip address in the setup for RTPPROXY and Kamailio ?

Kamailio

!define PUBLIC_IP "xxx.xxx.xxx.xxx"

!define PRIVATE_IP "192.168.1.19"

!define PRIVATE_NET "192.168.1.0/24"

RTPPROXY

Defaults for rtpproxy

The control socket.

CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock"

To listen on an UDP socket, uncomment this line:

CONTROL_SOCK=udp:127.0.0.1:7722

Additional options that are passed to the daemon.

EXTRA_OPTS="-l $ipv4private/$ipv4public -m $rtpport_min -M $rtpport_max -d $syslog"`

About RTPPROXY, do I need to assign ONLY the public ip address and/or private ip address ?

Best Regards

Hello, both public and private. Otherwise RTPPROXY won't be able to bind the the local address.

Dear @davidcsi

Thanks for the reply.

In my setup I have only one NIC then I need to add both ip (pub and private).

In other setup I have 2x NIC, one for the internal access of sip codec and the second is for the external access then ?

In RTPPROXY do I need 3x IP? One for internal, one for external who will be NATTed and third for public IP ?

Best regards

Dear,

I still have some issues.

  1. The sipphone on the private network continue to send INVITE even the RTP is enabled
  2. after 30S, the sipphone on private network send a BYE and close the communication

Let me know if you need more logs.

Entity on the public IPs is not ACKing the 200 Ok so the call ends after 30 seconds.

Get a trace from the public side and look at why the public io is not confirming the 200.

Please post a trace (text based).

Two sipphone on same network (private) everything are ok

One sipphone on private and One sipphone external IP (4G Mobile), after 30s the connection close.

I captured the transaction and I can see that.
