1.3 is planned for November-December time frame.

I'd say asterisk is easier to understand because it follows the 
traditional PBX model, whereas openser is a real SIP proxy. You need a 
basic understand of how SIP works in order to deploy openser. One should 
e.g. be familiar with the differences between SIP transactions, dialogs, 
and sessions.

I've worked with many different SIP proxy products, commercial and open 
source, and openser/ser is by far the most flexible one. There is always 
room for improvements, but you won't find another proxy that provides 
such low level access to the SIP message routing engine.

Asterisk, on the other hand, works on a much higher layer. All you can 
do is modifying calls, you don't get access to individual SIP messages.
This simplifies the configuration but limits its usefulness.
