[Asterisk-Users] Echo - UK Impedance problem with X100P?

[Chris Blunt]

Hi Soren, 

Thanks for your reply on this.  My card is a clone, with an Ambiant 3200
chip.  The parameter you gave me has sorted out many of my problems.

It is people such as your self who are incredibly helpful within the
Asterisk community.  

As like many others, I am relatively new to Asterisk and appreciate help in
getting my proof of concept system up and running.

Thanks again

Chris

UK is a CTR21 country and after having a closer look at the wcfxo.c code it
is supported *if* the card have the global chipset (Clone only, I believe).

To enable CTR21 you have to modprobe/loadmod/whatever the wcfxo driver with
the parameter 'opermode=1'.
