We'd like to forward the source address that a request came from in a header, something like:
X-Source-Address: 192.168.1.1
Is there a neat way to do this? An append_sourcehf( "X-Source-Address" ) would be ideal. If worst comes to worst, we can always extract it from the c= after doing fix_nated_sdp(), but we'd prefer something less ugly!
Hi,
1. Which requests will you apply this rule for? If it's a INVITE, then you can always utilize existing Contact header, which is attached to every INVITE request.
2. SDP is definitely not an ugly way to extract source address. So, you can use this method without any doubt.
3. Why dont you attach a header at the client-side? (though SER might as well strip it off after forwarding)

Andrey,
We'll be using it for authentication, so can't trust anything from the client. We only care about INVITEs.
SDP seems the best so far.

You can use (with the CVS head version) functions from avp and xlog modules:
xlset_attr("source","%si"); append_avp_hf("X-Source-Address","source");
