<div><br>
</div>
<div>I'm currently developing an OpenSER module which does some
business logic for the company I work for. For compatibility
reasons we are working with openser-1.2.2-tls and we haven't
been able to upgrade to newer version yet.</div>
<div><br>
</div>
<div>In one block of the code I have to read an avp which is
written inside the openser.cfg script using:</div>
<div><br>
</div>
<div>OPENSER:</div>
<div>avp_copy(<a class="moz-txt-link-rfc2396E" href="sip:123@123.123.123:5060">"sip:123@123.123.123:5060"</a>,
"$avp(s:selectedroute)/g"); </div>
<div><br>
</div>
<div>C CODE:</div>
<div>
<div>if (is_response && is_invite_seq)</div>
<div>{</div>
<div><span style="white-space: pre-wrap; "> </span>struct
usr_avp* destavp <span style="white-space: pre-wrap; "> </span>=
NULL;</div>
<div><span style="white-space: pre-wrap; "> </span>int_str
destval;</div>
<div><span style="white-space: pre-wrap; "> </span>const str
selected_route <span style="white-space: pre-wrap; "> </span>=
{ "selectedroute", 13 };</div>
<div><span style="white-space: pre-wrap; "> </span>int
attempts = 1, max_attempts = 3;</div>
<div><br>
</div>
<div><span style="white-space: pre-wrap; "> </span><span
style="white-space: pre-wrap; ">for ( destavp =
search_first_avp(AVP_NAME_STR | AVP_VAL_STR, (int_str)
selected_route, NULL, 0); destavp != NULL; destavp =
search_next_avp(destavp, NULL) ) { get_avp_val(destavp,
&destval); }</span></div>
</div>
<div>}</div>
<div><br>
</div>
<div>The problem is that "selectedroute" avp cannot be found so
I can't read its value. This happens sporadically and most of
the time the code works just fine. </div>
<div><br>
</div>
<div>I also checked for the list of available AVPs using
get_avp_list() but it reports an empty list. </div>
<div><br>
</div>
<div>Is there another way to read AVPs or is there something I'm
missing which is causing this problem? <br>
</div>
</span></blockquote>
If the avp list is null inside C code, then the avp was not added.
Do you see any error message in syslog related to avp_copy()?<br>
<br>
After avp copy, do a xlog(..) line printing the avp, if it is
printed in syslog and you don't get it in C, then would be very
strange...<br>
<br>
Cheers,<br>
