[Asterisk-Users] Sipura-SPA2000 background noise

[Steven Kokinos]

I too have the same problem on a few units, but not on others. I also 
have been having difficulty hooking up multiple lines from one Sipura 
to the same multi-line phone system (seems to create a line cross) but 
have no problems with either cisco or dlink boxes. In general they are 
nice units, but I suspect they may have had a batch go out that were 
"noisy".
