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.

Do you have callprogress=yes and/or busydetect=yes in your zapata.conf
file?  If so, turn those settings off for your E1 channels.  They're the
most likely cause for disconnects during a call.
