It can be merged, but the retrieval of current r-uri has to be changed. I don't think it is wise to use config variables names in the C code. I refer to the snippet:

``` + str src_uri = str_init("$ru"); ... + if (pv_eval_str(msg, &ruri, &src_uri) < 0) { + LM_ERR("Failed to get $ru value fallback to parse msg\n"); + ruri.s = REQ_LINE(msg).uri.s; + ruri.len = REQ_LINE(msg).uri.len; + } ```

It should be as simple as:

``` if(parse_sip_msg_uri(msg)<0) { /* error handling */ }

if (msg->new_uri.s!=NULL) { ruri = msg->new_uri; } else { ruri = REQ_LINE(msg).uri; }

```

The name of r-uri variable (**$ru**) is set by pv module, I don't think sca (or other module) have to rely on that being forever. Also, it requires parsing the name and evaluation. In cases when there is a lot of duplicated code, better export the C function from pv module and make that a dependency, otherwise this approach can hide unpredictible behaviour in long term, without getting any errors at compilation or linking.

Yep, all ok. I was looking for that macro, but didn't remember the name and no time for deeper search ...
