[Spce-user] Fail-over SIP Trunk

[Daniel Grotti]

Thanks Barry,
You are right. I mixed up the  priority.
Lowest q-value has less priority that highest q-values.

Regarding floating point, yes, it is indeed. But from the panel, if you 
set integer value, like 1, it will store the corresponding floaintg 
value 1.0. As it is a floating point, you can set values from 0.1 till 1.0.
