[OpenSIPS-Users] fr_inv_timer: description in the documentation is misleading

[Andrew Pogrebennyk]

Hi,

 From http://www.opensips.org/html/docs/modules/1.5.x/tm.html#id228479:

fr_inv_timer (integer)

Timer which hits if no final reply for an INVITE arrives after a 
provisional message was received (in seconds). This timer is started 
after the first provisional response. Thus, fast failover (no 100 trying 
from gateway) can be achieved by setting fr_timer to low values. See 
example below

Isn't there a contradiction between 2nd and 3rd sentences? If the timer 
is really started after the first provisional response (e.g. 100), it 
can't affect the time we wait for the receipt of 100 from the gateway. 
Of course source code will clarify this for me, but I just want to point 
out this mismatch. Thanks!
