Module: sip-router
Branch: master
Commit: 148b8faa4c38115bbe47809f0921fd20f86c6567

Export picked branch index via the tm module API.

This patch turns a function-local variable into a global variable in the
module and adds a new function to read the value of the variable. The
function is then exported via the tm module API.
