[Asterisk-Users] X100P behind an ADSL filter?

[randulo]

Hello,

I have an X100P connected to a phone line that is used for ADSL. The DSL 
modem is connected directly to the wall jack. A regular phone was 
connected on this line through an "ADSL line filter".

The audio part works with * just like it does on the phone, but it 
appears callerid is not coming through the filter. Could someone here 
who knows lots about POTS systems and the ADSL filter please say if the 
filter would be interfering with this function? Callerid does work on 
our other line.
