Dear List.
I'm trying to change the contact header of a message. ( by calliing add_contact_alias
- that shuld add the ;alias= parameter to the contact header)
but, when i print the contact header (with xlog), it shows no change.
I know the function works, and that it added the parameter as expected by using debug
mode. (it sais that it was added)
Can anyone explain me why i don't see that change in the xlog ? (i've printer
both $ct and $hdr(Contact))
Kamailio keeps two buffers of the incoming message, one is a copy of the incoming and the
other one
is the one where changes happen, a template for any outbound message used when forwarding
to the next hop.
If you change headers, they are changed in the outbound buffer, not the incoming. When you
use
functions to check headers, you check the incoming buffer.
There is a function to apply changes to the inbound buffer that is needed sometimes, but
very
few times. It can be quite confusing if you are not aware of how changes to messages are
applied.
