asterisk users - Jan 2005 - Void callerid info on iax clients, but OK from local extensions or on SIP clients

Hi,

first I wanted BT100 to display caller id properly. But on this way (BT100
now works) I lost caller id on all iax clients (Firefly, iaxphone) - when
call comes from outside CAPI line, although according to console callerid is
there (only number).

Are there any special hints on displaying CallerId info on iax clients ?
Anyone has working example ?

Thanks in advance,

Rob.
