[SR-Users] Kamailio proxy for far-end nat traversal

[rahul.ultimate]

Hi Daniel

I have rtpproxy to perform media relaying.

The case where it just timeouts: 
1. Client A behind NAT (wifi) calling Client B on 3G

Hello,

do you have rtpproxy or rtpengine for relaying rtp packets? Kamailio is routing only sip packets, you need the rtp relay application to help with media streams.

Cheers,
Daniel

Hello

I need a small guidance on creating a light weight proxy which only forwards the msgs to my sip server and also does supports symmetrical nated clients.

The way I have created the configuration is a slight modification of :
https://github.com/xlab1/sipfe_kamailio/blob/master/kamailio.cfg

Problem is unless the sip clients use STUN media packets are not routed. And sometimes even the signalling does not pass through.

Should i not use fix_nated_register and switch to fix _ nated_contact always ?

Because in all those cases where signalling does not pass through, I see RTO. My best guess is kamailio trying to communicate with private ip.

Anything which I can try that you could suggest from the top of yourmind woyld be muc appreciated. 


Thanks
Rahul
