[SR-Users] Kamailio SIP TLS Troubleshooting

[Henning Westerholt]

Hello,

if the requirement is to send this from android – then maybe ask at the android client project or vendor. I can’t help you here, sorry.

If the requirement is to send this from Kamailio, there were already some suggestions done in this e-mail thread.

Cheers,

Henning

Hi Henning

My SIP message which are received by my kamailio is already TLS Encrypted from my android Client ( Handset) but I have requirement to forward
these SIP messages from android client to a port mirrored destination ( say a Probe).

Cheers

Hello,

Not sure if I understood you correctly. The SIP message data is not encrypted inside Kamailio, otherwise it would not work to parse the packet etc.. So you can access it and also forward it unencrypted to another destination.

Cheers,

Henning

Hello,

you could mirror the SIP traffic also with t_replicate function from the TM module in the cfg.

Cheers,

Henning

Hi Experts.

Need your opinion on below part related to kamailio

I am using SIP Kamailio module Version for the SIP Registrations from the  Client mobile phones using Android and IOS which is Over TLSv1.2 , So in nutshell the SIP Signaling is TLS version 1.2 encrypted and Customer is requesting for the forward of the  unencrypted SIP signaling messages especially the SIP Registration messages  to their probe solutions without storing the SIP messages locally in the Kamailio Database

Question  :Would it not be possible for Kamailio   imply “mirror” all the SIP messages related to all SIP REGISTER dialogs (after removing TLS for inbound messages and prior to adding TLS for outbound message) to a designated IP Address and Port?  No need for local database storage.  No need for encapsulation.  No mirroring of other messages/dialogs.

Cheers
