[asterisk-biz] How to make TE220B work well?

[sunxiujun26 at sina.com]

hello everyone,
     I used trixbox 1.2.3 with a E1 card(not digium).The call often disconnected,and the echo is great.
     Recently, I bought a E1 card from digium --TE220B. It can not work on trixbox 1.2.3. The "te200series-user-manual"  says the card need asterisk 1.2.20 or newer and zaptel 1.2.20 or newer, so I update trixbox1.2.3(asterisk 1.2.12 and zaptel 1.2.9) to trixbox 2.2 (asterisk 1.2.24 and zaptel 1.2.21).But the disconnected rate increased much,the sip_phone can not be used.
     I don't know if I chose a wrong release ,or I don't use the card correctly. I want somebody can give me some clews.
     Thank you in advance!

Best regards!
