Hi all, looking for some advice on a good FXO solution for Asterisk, living in the UK brings some issues (as Asterisk and associated hardware appears to be geared to the US/Canadian market) such as calling line ID, impedance settings and echo cancellation (as a result of the impedance issues). I originally went down the route of an X100P which after applying the UK CLID patch worked fine (good sound levels and quality) except the echo issue. I decided then to follow the Sipura SPA-3000 route as this theoritically answered all my problems, unfortuntately the sound quality is appalling (see - http://voxilla.com/index.php?name=PNphpBB2 <http://voxilla.com/index.php?name=PNphpBB2&file=viewtopic&t=474&postday s=0&postorder=asc&highlight=3000+quality&start=0> &file=viewtopic&t=474&postdays=0&postorder=asc&highlight=3000+quality&st art=0). So I guess the obvious choice would be the TDM400 with FXO daughter board, I assume this works with my current zaptel drivers and UK CLID patch? Can anyone confirm this works fine in the UK or are there other suggestions? Regrads, Ray -------------- next part -------------- An HTML attachment was scrubbed...

I have noticed this on calling in but it is not major and a lot of it is possibly to do with the lack of quality on my BT line as a previous non VOIP switchboard plugged into the line was equally quiet (although with a hardwired phone it seems fine).

Digium are aware of the problem, but fixing it doesn't seem to be a high priority, despite the fact that they have been supplied with detailed technical information regarding BT line behaviour :-(. FWIW, I find the Sipura 3000 works well for me here in the UK once configured using their on-line web tool. Patrick

I just bought a DigitNetworks card called "DigitNetworks X100P - FXO PCI card" which supposedly is compatible with the discontinued Digium X100P card. This is a single port FXO card. Tell me how to test for the TDM400 problem and I'll perform a test and post my results back to the list. The card is dead cheap $25 (but $36 :-( for shipping ).

I find the voice quality fine on the 3000. Have you set the line Z etc correctly and used ulaw?

I had a look at it and...yes it seems to be the same card and it costs much less then I payed for it :( - j - ________________________________ From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Razza Sent: 26 April 2005 17:16 To: 'Asterisk Users Mailing List - Non-Commercial Discussion' Subject: RE: [Asterisk-Users] Good FXO for UK use.

I can confirm that the X100P and clones do correctly detect hangup on the BT network, but are plagued by echo problems due the impedance mismatch with the UK phone network. Patrick
Patrick Worte: The problem is indeed unique to the TDM400 FXO daughter board. I can confirm that the X100P and clones do correctly detect hangup on the BT network, but are plagued by echo problems due the impedance mismatch with the UK phone network. Ok I might be beingd really dumb here, but if Digium wrote the firmware for the X100P and the TDM400...why on earth has this feature been omitted? Also do we know if it is going to be rectified? Ray
