Hello,
the corex has a function to tell if the message is received by kamailio
or sent out:
- http://kamailio.org/docs/modules/devel/modules/corex.html#idp29928
If you interconnect with other servers/gateways when you don't what to
do special encoding, then you need to test src ip or look ar r-uri/dst uri.
Cheers,
Daniel

Hi,
Did you get some free cycles to look at it ?

Thanks for replying !
But how to check whether a particular message received by Kamailio
was sent by UAC or SIP Server ?
Also, on the same lines - how to know whether a particular message
about to be send from Kamailio is bound to UAC or SIP Server ?

Hi,
The network io intercept feature basically allows kamailio
script writer to do whatever s/he may want to do with raw SIP
packets (that are just received by kamailio or about to be
sent out by kamailio), e.g. encryption, compression or any
final touches to sip message before it is processed by
kamailio core. That is why it is purposely kept abstract and
any particular use or implementation is left to the script writer.
In your case the encryption / decryption code is in C/C++, you
can try one of the followings,
1. Writeup a C/C++ program that receives outgoing SIP message
as text (and some other parameters, e.g. encryption key) in
input arguments and returns the encrypted message in
event_route [ network:msg ] and vice versa (for incoming
messages). You can call this program directly from
kamailio.cfg script.
2. Writeup e.g. a PERL wrapper for your encryption /
decryption C/C++ code and call it using kamailio app_perl
module within event_route [ network:msg ] as demonstrated in
this example,
http://kamailio.org/docs/modules/devel/modules/corex.html#idp125704
You can also use any other kamailio language bind of you
choice as well, e.g. Python, LUA, JAVA and so on.
I would recommend the second option, as it has less processing
overhead for kamailio.
Thank you.

Hello,
I was going through the new features and stumbled upon
this new one - developed by Mohd. Shahzad Shafi.
As already mentioned on the wiki about this module, I
intend to use it for my custom security layer between UACs
and SIP Proxy (Kamailio) but the issue is - the custom
security layer (encryption/decryption code) is written in
C and should precisely be applied for the messages between
UAC and Proxy.
Is there a way I can achieve this using Corex module since
it does intercept the network I/O messages ?
Any help here would be really appreciated.
