[Asterisk-Users] PRI echo

[Jason Kim]

Hi,

My configuration is pri----*(te405p)---iaxclient.
My * version is 1.0.7 running on tyan dual opteron
board.
I have several problems.

1) inbound echo
For outbound call(iaxclient-->pri), there is almost no
echo. But for inbound(pri-->iaxclient), I can hear
distinct echo. Can Sangoma a104 or digium te406p help
this problem? 

2)Today i received te406p. I know T1/E1 jumper. But
how can i change the configuration of te406p for echo
cancel mode selection?

3) asterisk crash

4)chan_iax2
Some times asterisk log file is filled with strange
message as follow.
Sep  8 13:36:41 NOTICE[4339]: I should never be
called!
Sep  8 13:36:41 NOTICE[4339]: I should never be
called!
And some times it's overloading my sata HDD and 
disable ssh connection.
