asterisk users - Feb 2005 - Teles PCI and chan_capi, possible ???

Hello!

I'm curently using * with two old Teles PCI card (wich, btw, were hard to
install and make good use of) with ISDN4Linux.
The sound quality is simply perfect.

However both dialing in and out through the ISDN line, there seems to be a
_little_ bit of echo that eventually gets on your nerves !
Also the echo seems to get a _little_ bigger after a minute or so into the
conversation.

Now, googling through this list, all related messages I can are -- "install
chan_capi" over and over.

I'ld install it, but it was designed for AVM Fritz cards and I don't
know if
these Teles PCI are compatible or not.
Also, on my previous attempt to install and run chan_capi, I didn't get it
to work because I never got to initialize CAPI correctly before running
Asterisk.

Is there an easier way to cancel the echo ?
Is there a way to use chan_capi with Teles cards ?

Thanks in advance

Hi,

If your cards are supported by i4l, the odds on support in
mISDN are good. mISDN provides a CAPI interface for the
cards. Maybe you should check that out.
My experience with the echo on i4l is the same and it all
went away once switched to CAPI.
Good luck.

btw, you can find more on mISDN here:
