RE: [Asterisk-Users] Good FXO for UK use.

Title: Message
Got a feeling that the same card I bought from goods2world.co.uk, which gave me terrible echo problems, due to the impedance mismatch of the US telco network (600ohm) versus the BT network.
 
When using that card all seemed to disconnect fine, I assume the issue lies with the TDM400/FXO daughter board.

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 ).

This maybe an out of place comment but it would appear Digium show little to no interest in non-North American implementations, do we know if they are ever going to resolve this issue? or indeed how much it would cost? Based on my experience I'm sure there are a number of UK based people who could jointly fund such a development for a reasonable FXO product?

No the TDM400 does not work, it does not detect calling party termination correctly, so IVR and voicemail do not see the caller hang up on BT lines. 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 :-(.

Patrick is right about this , I get 20 or so seconds of solid tone at the end of all my voicemails,
but I can live with this for the sake of no echo.
