Imagine during CPL a user A is called and its UAS replies:
  302 Moved
  Contact: B

If "proxy_recurse" >= 1 then CPL will "eat" that 302 and instead of forward 
upstream to the UAC it will generate a new branch to B automatically.

Now B is called but it also replies:
  302 Moved
  Contact: C

"proxy_recurse" = 2 so this second redirection is allowed and OpenSer CPL 
module will "eat" this 302 and generate a new branch to C.

Now C is called but it also replies:
  302 Moved
  Contact: D

"proxy_recurse" = 2 and this is the 3th redirection received by this CPL 
executin, so it won't "eat" it but forward the 302 upstream to the call 
originator.
