- 1.2.0 got better timer granularity. The accuracy of SIP retransmission timers can be set at millisecond level...

From the announcement:

" OpenSER devel branch has now core support for timers will resolution less than a second. It uses time functions that can give a microsecond accuracy, but for performance reasons, the utimer (microtimer) uses a ticking period of 100 milliseconds. Of course, this can be changed at compile time.

First "beneficiary" of this timer, is TM, to gain more accuracy for retransmissions:
* retransmission timers use the the core utimer (with microsecond resolution),
 having 100 milliseconds intervals.
* this will increase the retransmissions precision to an error of maximum
 100 milliseconds."

Along with that, timers of TM module have been improved for faster operations.
