Yes, but what happens when those modifications, or responses based on those modifications, are returned to the sender? Much as with most SIP headers, the sending SS7 gateway can well say, "I didn't send that."

Thanks Alex
the first thing that came to my mind is performing some number manipulation. Imagine kamailio acting as a router for several carriers.
One of them demands an international NOA with a weird prefix, whereas the other one, for the same destination, requires a pound (#) at the end, and so on. I agree with you in disliking idea of being too "invasive" in the body of the sip message, but it's something already doable for instance with SDP.

Hi Javi,
The first question to ask is: if Kamailio could understand ISUP parameters, what would it do with them?
If the answer is "not a whole lot", chances are it is something that only needs to be understood by the endpoints, and which Kamailio
would
continue to be agnostic to, as it is now. Kamailio is, above all else, a message relay.
