(open)ser is a SIP proxy, not a SIP stack. They include of course a SIP 
parser, bit this is not well suited for use in other application.

Thus, if you are looking for a SIP proxy, (open)ser is a good choice. If 
you are looking for a SIP stack then you might take a look at

ser and openser are IMO both not easy to use - configuration can become 
real complex - there is no big difference between ser and openser.

Recently there were duscussions about the which proxy performs better. 
IMO in a real usecase the performance heavily depends on the performance 
of the backends (database, radius) thus there wont be great differences 
between ser and openser.

Both ser and openser have the pa module. This is rather old and buggy - 
do not use it.

ser CVS as well has openser CVS has new presence modules which are 
totally different. I haven't used either of them. Thus, you have to use 
both and compare it yourself.
