Re: [Asterisk-Users] Best drivers for HFC-S ISDN cards
Chris Looking at this file below you need to move the stuff below the channel => 4-5 line to each span definition. Anything below the channel line gets completely ignored! I stand to be corrected but I think your current config will not have any echo cancellation at all. I have just posted my own zapata.conf files to this list. Take a look.

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. Best regards Tim Robinson Basingstoke, UK Chris Bagnall wrote: It seems that HFC-S cards can be connected with asterisk in a few different ways - isdn4linux, mISDN, chan_capi or zaphfc.

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?

Re: [Asterisk-Users] Best drivers for HFC-S ISDN cards
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? CAPI doesn't work with this card. mISDN should work, but zaphfc should prolly be fine as well. isdn4linux will probably work, and give you a long term headache, nausea and possibly hemroids. you may want to tune the echo cancellation in zaptel (echocancel=256 or something) to see if that helps... roy ___ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
