<p>Hello,<o:p></o:p></p>
<p>the separator has to be a single character as documented:<o:p></o:p></p>
<p> * <a href="https://www.kamailio.org/wiki/cookbooks/5.5.x/transformations#sselect_index_separator">
https://www.kamailio.org/wiki/cookbooks/5.5.x/transformations#sselect_index_separator</a><o:p></o:p></p>
<p>It does not support variables.<o:p></o:p></p>
<p>Looking at the code, it also does not support escaped characters, probably this feature can be useful to introduce.<o:p></o:p></p>
<p>Cheers,<br>
Daniel<o:p></o:p></p>
