Hello, I have played with the SPA-3000 a bit, but I haven't used the HT488. Pros: The Sipura device is extremely configurable, with many fun options. It can be used as two completely separate sip devices (one FXO and one FXS), and optionally provides failover (directly connecting the FXO/FXS) during loss of power or network. It's well suited to mass deployment, if you require this. It has many internationalization options for FXO/FXS port impedence, tone schemes, hangup detection, and so on. Cons: Many people have complained about Sipura customer support being unavailable for end users. Personally, I try to avoid the problem by not needing support whenever possible... however: The main complaint I have with the SPA-3000 is the sound quality and volume on the FXO port. When a call is made between the POTS line and another phone on the Asterisk server, the sound volume is very low, and there is an intermittant popping/clicking sound on the line. I have tried tweaking many of the settings (VoIP/PSTN gain) in the device to rectify this, but so far I haven't been able to make it better at all. I have heard others with a similar complaint, but I haven't heard any resolution for the problem yet. Thanks, Alan Ferrency pair Networks, Inc.
