[Asterisk-Users] sipura over heat

[Steve Dolloff]

We have seen this symptom occur in about 3% of our SPA-2000 units.  One
in particular, I know was lying upside down for a couple of hours before
it started happening for the first time, so I also believe it is heat
related.  Sipura has replaced the defective units.
