Dear All
When 200 OK to INVITE passes through Kamailio proxy , I want to change the
IP address in SDP to a specific IP address.
Can this be done by just modifying configuration files or do I need to
modify in source code.
In case I need to modify source code, which files I need to look at.
Kindly provide pointers for said problem.
Thanks
Austin

You can modify ANYTHING in a text based attachment like an SDP in the configuration
script.
To make it a bit simple for you, we have two modules that work with specific parts:
- SDPops http://kamailio.org/docs/modules/devel/modules/sdpops.html
- MANGLER http://kamailio.org/docs/modules/devel/modules/mangler.html
In the Mangler module there's a function called "sdp_mangle_ip()" that will
make you happy.
You can always copy the whole SDP into an AVP with SDP_GET, use the transformations to
read one line at a time and modify it.

Dear Ole
I am not finding any example how to do it (changing a fqdn with ipaddress
in sdp).
Using sdp_get i can get the sdp.
But how i can use transformation function pls let me know.
The sdpops link does not give much info how to modify any line.
Best regards

Looks we do not have any option to modify a FQDN that comes in 200 OK of
INVITE's SDP.
One need to modify the source code to achieve this,.., ya not a good idea
though....

You asked for
changing the IP and you do that with the function in mangler.
In SDPops you get the attachment, the SDP, into the AVP. Then change it using string
operations and transformations and add it back to the message - request or response.

You asked for
changing the IP and you do that easiest with the function created to do just that in
mangler.
In SDPops you get the attachment, the SDP, into the AVP. Then change it using string
operations and transformations and add it back to the message - request or response.
It's pretty normal scripting. Use the transformation to get the number of lines in the
avp, use a while loop and pick out each line, do the changes if needed. When you are done,
use the set_body() function in the textops module to add the new SDP to the message. In
the textops you also have a function named replace_body_stonce() that can do the trick for
you. In short, there are many ways to do it, but you will have to read documentation :-)

I hope if I am changing IP address to another IP address sdp mangler works
fine.
If I want to change a FQDN that does not work.
I did not understand "ou can always copy the whole SDP into an AVP with
SDP_GET, use the transformations to read one line at a time and modify it."
can you please elaborate it.
Many thanks for your input.
