[OpenSIPS-Users] overwriting AVPs at certain index

[Bogdan-Andrei Iancu]

Hi Jayesh,

Just tried the following script and it did the right job:

<snap>
    $avp(s:value1) = "abc";
    $avp(s:value2) = "ABC";

    $avp(s:variable) = $avp(s:value1);
    $avp(i:999) = 0;
    $(avp(s:variable)[$avp(i:999)]) = $avp(s:value2);

    avp_print();
</snap>

and the result (from avp_print()) :

Can you post the error/log you get?
