[Asterisk-Users] dreaded Caller*ID failed checksum

[Bisker, Scott (7805)]

Did you install the micro filters that came with with your ADSL modem.  Usually you get 3-4 of these.  They are used to protect your analog lines from the additional signal noise from the ADSL signal.

Some input for those with bigger brains like, perhaps, Jeremy Hall, to ponder in relation to the Caller*ID failed checksum message. 

1.  I have a Digium X101P (and TDM420P) 
2.  I installed in January and had no problems with Caller ID 
3.  I played with Asterisk including a few CSV updates in February (stable 1.0, I think). 
4.  Then I had problems with Asterisk never reporting Caller ID to phones on the TMD420P and returning the "failed checksum" message sometimes. 
5.  I updated to Apri 4 CSV of zaptel and asterisk and now Caller ID works. 
6.  I have ADSL, which introduces noise on the line and I have an emergency phone which bypasses Asterisk (in case of power failure).  That phone reports Caller ID without problems. 
7.  Now the X101P fails to detect hangups reliably, though I think it is more reliable than it was in March when I was using the stable code.
