RE: [Asterisk-Users] HT-488 vs. SPA-3000?
I've been looking into this more for a small deployment. Is it at all possible to put some other line adapter to amplify/increase signal before it goes into the spa3k? Something like these? (Found these after a quick google search) http://www.harriscomm.com/catalog/default.php?cPath=1141_47_167 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemcategory=1503item=5784527504; rd=1ssPageName=WDVW Would love to know if anyone has tried them. Thanks John Cianfarani --- I had exactly the same experience with the SPA-3000. Too bad too since it's nice device...if it were 6 db hotter. I also installed a TDM-400, which was better in a lot of ways but not perfect. When I rebuild my server I ended up simply call forwarding my POTS lines to a DID provided by an ITSP. This has been the best as far as quality is concerned. If my DSL line goes down I simply defeat the call forwarding on the main line and answer an analog phone for a while, or call forward to me cell.

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.

RE: [Asterisk-Users] HT-488 vs. SPA-3000?
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.

RE: [Asterisk-Users] HT-488 vs. SPA-3000?
The majority of the audio level issues seem to be on the fxo port and setting the transmission levels (gain) to compensate for the cable loss to the central office. Eg, setting the pstn gain values to what should be appropriate causes echo, etc, not unlike the TDM card. (I have both in use.) In other words, the further the spa3000 (or TDM card) is from the central office, the more difficult it seems to be to set gain values that are acceptable.

Perhaps there is something else going on the the Sipura 3000. Its voice quality and volume so poor/low that the device FXO port is not usable. However, same everthing and the TDM400P card works perfectly with excellent voice quality and volume. My experience, obviously just one data point.

It is sort of like the old telephony talk off that existed years ago. Doesn't happen all that often and seems to be more sensitive to female voices based on my one-year of experience. 2. sometimes it seems to operate in half-duplex mode, where if you try to talk at the same time as the other end is talking, the other end won't hear you. Neither one of those have been all that objectionable to me, but they happen and others have posted roughly the same issues. I've not heard of anyone that has found a way to minimize those two issues. The down side of the spa3k right now is that Cisco bought the company and there likely won't be much advancement of the code until after the ownership (and development efforts) are sorted out by both companies. (The same kind of product delays has been seen with their Linksys purchase, as well as when other companies are bought/sold.) Its fairly common knowledge that ex-Cisco folks started Sipura for the sole purpose of selling the company for a hugh profit. Their success in accomplishing
RE: [Asterisk-Users] HT-488 vs. SPA-3000?
The only thing that snaps to mind is the interesting wiring in the building. The phone lines come into a 66 block, then are jumped across 3 more 66 blocks, then over to a 110 block, then down to another 110 block, then finally down into the Sipura3000s. The 66 and 110 blocks feed the old analog system around the building. The lines aren't connected to phones at the other ends, but they were left in place as a fallback position. It's a manufacturing facility so I suspect there could be some interference in the building crossing into the phone lines. I'm planning on wiring directly from the Qwest 66 block into the SPA3000s and disconnecting the rest of the phone system on my next visit. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Dan Littlejohn Sent: Wednesday, June 15, 2005 2:04 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] HT-488 vs. SPA-3000? Perhaps there is something else going on the the Sipura 3000. Its voice quality and volume so poor/low that the device FXO port is not usable. However, same everthing and the TDM400P card works perfectly with excellent voice quality and volume. My experience, obviously just one data point.

At everything from the default to the maximum in positive and negative values, and combination of gain settings, we still get unacceptable distortion and echo.

The majority of the audio level issues seem to be on the fxo port and setting the transmission levels (gain) to compensate for the cable loss to the central office. Eg, setting the pstn gain values to what should be appropriate causes echo, etc, not unlike the TDM card. (I have both in use.) In other words, the further the spa3000 (or TDM card) is from the central office, the more difficult it seems to be to set gain values that are acceptable.

I live out in the woods. Sorry you guys have all these problems, but mine is perfect outside of the occasional talk off. Same here. When I mentioned distance from the central office, I probably should have mentioned distance from the Remote Line Cabinet (or whatever your local telco might be using). Just about every telco now deploys concentrators of some sort that essentially makes it look like you are much closer to the central office then what you actually are. Its the transmission loss that occurs over copper cables (where ever the other end of that happens to be in your case) that seems to be the key. When viewing your spa3k config via the PSTN tab, what do you show for SPA to PSTN Gain, and, PSTN to SPA Gain near the bottom of that page? If those values are small and you wife is okay with audio levels, then you're not far from the central office or remote line cabinet. ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Basically I'm looking for a FXO/FXS/LAN ATA and these two seems to be the top of the pick..Any comments and experiences esp. with Asterisk compatibility would be great, before I plonk in the bucks. 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.
