i too have been thinking that regex is an overkill for tests like

if (uri=~"^sip:\+") ...

a php like substr function might be faster.  so instead of the above or

 > i.e. strip_tail(strlen($ru) - 2); ... or something like such.

how about

if (substr(uri, 0, 5) == "sip:+") ...


substr($ru, -2, 2)

by the way, i didn't notice == operator in the summary.  should i write
the above if as

switch(substr(uri, 0, 5)) {
  case "sip:+": ...
  default: ...

instead or is == supported?
