Hi! I have problems with avp_subst: I have $avp(s:pai) with the value <tel:+43108> (the < and > belongs to the AVP) Then I want to extract the number into $avp(s:cli): avp_subst("$avp(s:pai)/$avp(s:cli)","/tel:(.*)/\1/") The result is <+43108> Can someone explain me why the leading < belongs to the result? Shouldn't it be removed? thanks klaus
