Topic: SAIL Compatible Hardware

[ntblade]

Just a thought...

Been catching up with the SAIL news on the Forum and it seems that we're still buying X100P clones.  I know Selintra should have stock of some working ones but do we have a database of hardware know to work in in what country?

Trouble is, the cheap ebay clones may be fine but in the UK / Japan (AFAIK) the impedance of the PSTN line is different from the US etc.  Now, what that means is the clone I bought from ebay doesn't have the DAA chip that can be programmed to match the UK impedance resulting in increased echo.

Whether Asterisk / SAIL's echo cancellation can get round this I dont know.

I'm about to embark on a fresh SME / SAIL build so I'll retry the clone I have and report back.

Meantime it might be worth starting a mini SME / SAIL Hardware Compatibility List (SHCL) or possibley a SME / SAIL WIKI.

THoughts?

Hi NT hope you are well...

Here's a quick hardware guide....

All Digium boards are supported except the B410P quadBRI card (which is only for the European market and won't work on US BRI).  It will be supported in SAIL 2.1.15 when Digium releases support for it in 1.4 (which I don't think they've done yet).

In SAIL 2.1.14 we also support HFC BRI cards through the use of BriStuff with the Florz patches added.   This includes all of the Junghanns BRI cards and most HFC based cards.  It works very well but can be a pig to mix with TDM boards (we have a couple of customers who have both on the same machine).  

In SAIL 2.1.15 we have dropped BriStuff in favour of mISDN and this allows us to support more boards including all Junghanns and Beronet  plus the AVM Fritz and most HFC based passive cards.  However, we have noticed that mISDN uses a lot more CPU than BriStuff so we wouldn't recommend it for small CPUs.  Also in 2.1.15, for cards that support it, we can run in both TE and NT mode allowing us to play a few nice games acting as a BRI/VoIP gateway to legacy PBX systems.  Herve did a very fine job in crafting the mISDN support.  In this release you can mix TDM, BRI and PRI cards with no restrictions.  

X100P clones will run and SAIL will load the wcfxo driver to cope with them.  Unfortunately, most of these cards are worth what you pay for them.  The sound quality is poor and you can't usually vary the impedance for your country unless you are very lucky.  You will also likely have echo problems, call progress problems and CLI detection problems.  However, they are great for learning and tinkering and they only cost a few bucks.

The OpenVox range of Digium clones will all run with SAIL.

We do not support the Sangoma range of cards and they will NOT run with SAIL without a great deal of work.

Lastly, we support all of the MultiTech analog, BRI and PRI gateways and they will all run "straight from the crate" with SAIL.

Oh and of course we support most of the FXO ATA gateways; Sipura, Grandstream and so on.

One to add to the list: DrayTek Vigor 2910VG security router. It has two FXS ports that tie in easily via general SIP. Also has built in QoS, not to mention a bunch of other handy features.

Fine, thanks

OK, What's the most economical way of integrating SAIL with the UK PSTN?

All the best,

HI NT

This is for BT lines ONLY.  We've never found anything that works reliably with NTL lines and you just can't get any info out of NTL anyway.

Cheapest would be the Linksys 3102 ATA at about 48 quid + VAT.  You can get one from our friends at Telappliant here...

http://www.voiptalk.org/products/Linksys+SPA+3102

Next up would be a Digium TDM01B which is a TDM400 card with a single FXO daughterboard fitted (room for three more).  It retails for £84.99 + VAT in the UK.

If you have an ISDN2E circuit then you can use any of the passive HFC boards mentioned above.  They cost new from about £100 up to £300-£500 for a top of the range DSP carrying card.

Thanks for the reply,  I'll look at getting hold of one.

OK, Just got 2 x SPA-3102 delivered to play with.
So, what versions do you receommend to get going with one.  I want:
IAX and PSTN to be handled by SME / SAIL.
My server is server only mode.

Help!
