[asterisk-users] test OpenVox B400P and junghans card for dahdi BRI wcb4xxp

[lizhong zhu]

hello, all of users:
after dig the code, i found that dahdi wcb4xxp is only for digium B410P. it has VPM hardware based echo cancellation, which  Junghans and openvox bri cards do not have. anyone can tell me how to disable the ec_write methond to support other HFC BRI cards?
regards!
zhu
