anyone have any experience using these in a single system with digital cards

I don’t have experience with the rest, except Chinaroby. I bought two cards,
(TDM410P & TE405P) from eBay. I have both bad experience!!
I run the latest dahdi 2.4.1 The LEDs on the TDM410P do not lite. Occasionally,
the FXS ports will generate lots of noise. The FXS modules indeed feel very hot.
It was a nightmare to install the TE405 as well. It was not recognized by
Elastix 2.0 If I use Elastix 1.6, the ports appear. However, I cannot make
outgoing calls. I finally downgrade to Elastix 1.5 on Dahdi 2.3. The
outgoing/incoming calls work but there are some “clicking” noise in the first
about 10s.

My client eventually refuses to accept this system. I have to replace the card
from another supplier. No more clicking noise. So far, it works well for the
past 4 months.
