[Asterisk-Users] Best drivers for HFC-S ISDN cards

[Chris Bagnall]

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
