Hello,

the selects were developed by SER guys in the past (when it was a separate project, 2005-2008), so I am not that familiar with all the features they support and the actual relation between header names and select paths. In this case I see that the dash '-' has to be replaced with underscore '_' in header name, but I guess there can be headers with underscore in name...

However, if you just want to take the value for header X-Digium-AppServer-Response-URI, you can use Kamailio's native pseudo-variable (pv): $hdr(X-Digium-AppServer-Response-URI)

If you need from the second header with same name: $(hdr(X-Digium-AppServer-Response-URI)[1]) . The index can be an integer or a PV holding an integer. If the value is negative, it counts from the end of the list of headers.

Cheers,
Daniel

I'm trying to use the is_present_hf function to detect the presence of a user-defined header and getting the following errors in my Kamailio logs:

2(12149) BUG: <core> [select.c:426]: run_select(): Select structure has not been resolved
2(12149) ERROR: <core> [lvalue.c:416]: lval_assign(): assignment failed at pos: (99,58-99,58)
2(12149) ERROR: <script>:

A quick Google search yielded no results for why this could be happening. Originally, I had my code in route[REPLY], but noticed that was not one of the paths it was listed as available in the textops document, so I moved it to request_route, but got the same errors. Does anyone have any feedback on how to move forward? My code snippet is below:

if (is_present_hf("X-Digium-AppServer-Response-URI")) {
$var(a) = @hf_value.X_Digium_AppServer_Response_URI[1];
xlog ("\n\nHERE RESPONSE URI $var(a)\n\n");
}

Thanks,
Kyle
