[Kamailio-Users] Dialplan regular expressions

Dear all, I'm having difficulties in the dialplan module. My problem is in the regular expressions added to the database. I tried some examples from previous users but they don't work for me. example: dpid 10 pr 100 match_op 0 match_exp ^123(.*)$ match_len 0 subst_exp ^123 repl_exp 0030 Previous example from Daniel that I found in user lists: s/subst_exp/repl_exp/ subst_exp - is regular expression that can be used to group parts of the input repl_exp - is used to build the output Example: you want to remove the first 0 and prefix +44 to a number: subst_exp=^0(.+)$ repl_exp=+44\1 Can someone provide an example that works with the latest kamailio please? Also where I can find more docs about dialplan? Thank you all Alex
