Hi Daniel Thanks a lot for kind response. For this requirement, I need - 1. When a message is received at Kamailio proxy, that message either will be sent to client side or to main proxy side. 2. If it is supposed to send to client side, then it should send in plain UDP. Also note that, when the message is received from clients it should be received in plain udp by Kamailio proxy. 3. If Kamailio proxy is supposed to send the message to main proxy side, then it should send using TLS. Also note that, any message that comes from main proxy, Kamailio should receive in TLS only. As I understand, the three optioned mentioned below in your mail, I can use either of one.

Do I need to take any additional precaution so that TLS stuff will work fine (actually will be working on TLS first time).

There are couple options: - rewrite r-uri ($ru) to contain the transport=tls and then t_relay() - set dst uri ($du) to the uri point to main proxy address having the transport=tls parameter and then t_relay() - use t_relay_to("tls:mainproxyip:port") Cheers, Daniel On 10/4/12 12:21 PM, Kamal Palei wrote: -- Daniel-Constantin Mierla -http://www.asipto.com <http://www.asipto.com/> http://twitter.com/#!/miconda <http://twitter.com/#%21/miconda> -http://www.linkedin.com/in/miconda Kamailio Advanced Training, Berlin, Nov 5-8, 2012 -http://asipto.com/u/kat Kamailio Advanced Training, Miami, USA, Nov 12-14, 2012 -http://asipto.com/u/katu

Hi Daniel I was just googling TLS support in Kamailio. Came across http://nil.uniza.sk/network-security/tls/configuring-tls-support-kamailio-3… , am just wondering if I have to go step by step mentioned in this link. Can you please advise if all of these are required? And I was looking at how do I rewrite the request uri. Where I can get the exact syntax for rewriting the request uri.
