[Asterisk-Users] DSL vs X100P

[Isamar Maia]

I am trying to forward an inbound call to go out through another X101P
and I get nothing but a noise like a helicopter sound...
Inbound and outbound are ok if done separately.
I already checked IRQs and they are fine.
Updated the drivers and asterisk and they seem to be ok too.
Turned on and off echo cancel.
Both lines are coming from an ISDN line,channels A and B respectively.
Should it be cable problem or another issue, in this case with ISDN lines?
