[Serusers] How Many Nines?

[Jiri Kuthan]

Personally I think the software itself is same or better than industry 
average.
The challenge for reliability is in configuration and network design. If 
you would like to make it really resillient against various hard 
conditions, you are going to spend quite some time on the network design 
and test with SIP UAs you are going to use if they can deal with it.
