[Asterisk-Users] TE410P zaptel Driver Situation

Dimitri-
I'm not sure about the message "Unable to forward voice" - I don't get that
one on my systems.

The frame "reject" messages are the same ones I was talking about - these
are load related, I'm pretty sure.

Dear Scott

with not very high load 30 IN/OUT line, i use only two span in this moment.
What is only warning? or not?
Thanks in advance
Dimitri
