Summary:                    Problem with RX bits on E1-CAS
Description: 
Dahdi 2.3.0
Boards tested
TE205 4th gen
TE205 5th gen 
TE405 4th gen
TE405 5th gen

Asterisk 1.6.2.6 with openR2

There is a problem with Dahdi (2.3.0) and/or wct4xpp driver when
configured in E1-CAS mode ( for mfc-R2 protocol )
After starting Dahdi service and BEFORE starting asterisk , spans go green
/ no alarms but on dahdi_tool the CAS bits from the RX side are either all
0000 , expected values (1101 or 1001) for some channels, or some random
values.
This is happening with BOTH 4th and 5th gen boards.

After starting asterisk 1.6.2.6 with the supported openR2 MFCR2, RX bits
still do not refresh, outgoing calls are not allowed, until 'something'
happens, either unplug and re-plug the E1, or an incoming call from the
telco , at that moment ALL channels change the RX bits to correct/expected
values.

It works fine with zaptel 1.4.10 and 4th gen boards. zttool Always shows
correct values on all channels BEFORE starting asterisk (* 1.4.18 fyi)
