- double evaluation using pv_evalx() - https://www.kamailio.org/docs/modules/devel/modules/pv.html#pv.f.pv_evalx - use an embedded script with inline execution -- eg app_jsdt doesn't have external dependencies and you can run a small javascript script where you can use local variables for index and construct the $sel() as you need, then pass that to KSR.pv.get(...).
