Also one more observation, we can set $avp(somevariable) in some route
segment but it mislead corex module while dealing with auto-responded
message like 100 Trying, ACK etc..
E.g.
SIP Client kamailio Media Gateway
| | |
| | |
| | |
|INVITE (Compressed) |
|------------->| |
| | |
| | |
| |Uncompress and send this request to gateway
| | |
| | |
| | |
| |in uncompressed way. set $si and $sp in some
| | |
| | |
| | |
| |$avp(variable)|
| | |
| | |
| | |
|100 Trying (uncompressed) |
|<-------------| |
| | |
| | |
|not recognized reason ?? |
| | |
| | |
| | |
| |network:msg[] corex module hits before and
| | |
| | |
| | |
| |since $avp(variable) is set
| | |
| | |
| | |
| |whose details are not matching with
| | |
| | |
| | |
| |mediagateway so sending message in
| | |
| | |
| | |
| |uncompressed. |
| | |
| | |
| | |
| |INVITE (uncompressed)
| |------------->|
| | |
| | |
| | |
| | |
This is partial flow just to indicate I have been struggling of.
Thanks,

Hi Eduardo Lejarreta,
Thank you for your detailed reply.
What you are suggesting holds good for all those messages hits any
of the route segment in the script. But my struggle starts while
dealing with auto-responded messages like 100 Trying, ACK and 200 OK
against the CANCEL message etc.
That's why I was thinking of implementing another pseudo variable
capturing necessary details and still available at [network:msg] event
route though it is meant to have only raw packets.
Also I can see corex module works in binary mode only, either to
compress/encrypt or decompress/decrypt. But Kamailio being a proxy
need to deal with gateways at one end and end user client at other (In
very general usage terms. though many more possibilities are there)
and the primary purpose for which it was written was to deal all these
custom manipulations between the end user client and kamailio but it
forces kamailio to treat the gateways in the same manner which I think
defeats in someway what kamailio has been doing so far. E.g.
client<----TLS---->Kamailio<---UDP/TCP----->External Gateways.
Olle,
Hope you can understand where I am heading towards.
Thanks & Regards,
Niraj

Hi Niraj.
Read module help:
"
Please note this event route is meant to prepare the message for
on-wire communication, e.g. to do custom encryption or decryption,
compression/decompression etc. of the message sent to or received
from remote host. Therefore, except text operations, no module
fucntions or pseudo variables are available in this event route.
"
Forget to access or change someother than $avp(msg) like $si or $sp.
But think $avp(something) is still available.
On that route you can do something like these examples:
1.- You can acceso $si and $sp if you previously have assinegd them
to an $avp(var):
(with $avp(source_ip) previously assigned on any other route)
event_route[network:msg] {
xlog("L_INFO","ONREPLY: NETWORK_MSG $avp(source_ip)\n");
}
2.- You can also try to search on headers and do something like this
event_route[network:msg] {
if ( !is_incoming() ) {
if ( $mb =~ ".*application/sdp.*" ){
if ( $mb =~ ".*c=IN IP4 194\.30\.0\.82.*" ) {
xlog("L_DEBUG","EVENT_ROUTE: NETWORK_MSG
'$mb'\n");
}else{
$avp(msg) = $mb;
$avp(msg) = "";
xlog("L_INFO","EVENT_ROUTE: NETWORK_MSG: DROP de
MENSAJE: '$mb' \n");
}
}
}
}
Hope this helps you.
Regards.
Eduardo Lejarreta.

Hi Olle,
Thanks for your reply. But I beg to differ that any other pseudo
variable available in this module apart from $mb and msg_avp. I
have already tried to use those variables but they all give <null>
value.
I think we must be talking about two different things. I talk about
the script language - are you talking about
C source code development?

Thanks,
