Hi
As requested here are my configs. I have 3 zaphfc cards - 2 in NT mode
and 1 in TE mode connected to the BT network.
I have a variety of phones - a Cisco 7940, a Snom 190, a Grandsteam
Budgie plus 2 cordless ISDN phones on one of the NT ports, and a Network
Alchemy Cybergear Gold on the other connected to some analogue phones.
no echo. nil. niets!
Please post a diagram of your system config and we can take a look at it
if you need some help.

Oggetto: Re: [Asterisk-Users] Best drivers for HFC-S ISDN cards
Chris
I have only ever used zaphfc drivers and for me they are perfect. Echo
has never been a problem. It would be helpful if you were to provide a
bit more information to the group about your configuration so we can try
and help you work out the cause.
Switching to capi or mISDN is unlikely to help and will almost certainly
be a retrograde step as far as I hear from these forums.

It seems that HFC-S cards can be connected with asterisk in a few different
ways - isdn4linux, mISDN, chan_capi or zaphfc. I've tried isdn4linux (severe
echo, reproducable on every inbound call) and zaphfc (intermittent echo,
disappears within about 30 secs of the call starting).
What's the recommended way to hook up these ISDN cards? Is switching to capi
or mISDN likely to remove the echo problem completely, or is this one of
those things one has to accept?
Thanks in advance.
Regards,
Chris
