[asterisk-users] Big problems with TDM2400 :(

Hello Fellows!

I have a TDM2400 and I can't put it to work. Every time it receive a call the Asterisk handle it and call the SIP phone; when people pick up the fone they don't hear nothing and the caller hear the phone rings and nothing happens. In Asterisk console I can see the message answered by the SIP's phone.
I lost a lot of time trying to solve this problem without success :(.

I got the following message when a enable the usecallerid=yes:

I've tested with the Zaptel 1.2/ Asterisk 1.2 and Zaptel 1.4.5.1/Asterisk 1.4.11 and got the same problem.
Debian Etch amd64.

Thanks for any help!
