We have 6 SPA3000s. The device is extremely configurable and works inbound/outbound with Asterisk with the latest firmware update with little trouble. However, we've yet to resolve sound volume and quality issues. The PSTN to SPA gain and SPA to PSTN gain along with FXS Port Input Gain and Output Gain settings have had no positive effect. The problem is entirely with the analog line adapter. VoIP calls from the analog phone to other VoIP destinations are perfect. We also have several SPA-1001s and SPA-2000s that have been running perfect since day 1.
Also Sipura support is nonexistant. Just our experience. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Dan Littlejohn Sent: Wednesday, June 15, 2005 9:55 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] HT-488 vs. SPA-3000? I have only had experience with the Sipura 3000 and I would agree with the voice volume problems. I have given up on it working properly (adjusted gains, impedences, firmware, etc), the voice quality is just to low to actually use. I actually purchased a second one thinking that the first might be defective. Would not recommend it because of the low sound volume problem. Talking on the phone is actually the point of the device so who cares how configurable it is if you cannot hear anything. I purchased a Digium TDM400P and have had very good luck with it.
