Hi I've hit a problem with sht_rm_name_re() in htable module. I was calling it like this: sht_rm_name_re("Dlg=>$var(callid)::tenant"); But when I used sipp to generate 600 concurrent calls for example, I called this function when receiving BYE. But it removed more entries than it should. Seems when removing removing some entry with callid 1-3798(a)192.168.60.80 <mailto:1-3798@192.168.60.80>, it also removed entries for [1-9]1-3798(a)192.168.60.80 <mailto:1-3798@192.168.60.80>. How do I add '^' in front and '$' at the end of the regexp string when calling this function please? Here I don't really need regexp in fact, just want to do an exact match. But I didn't find any other functions for deleting entries.
