[Pavel Jezek]

Hello, if somebody using this scenario in production successfully, 
please send me info, which ISDN card for asterisk server is usefull for 
me (Digium, Sangoma)?
my crucial requirement is "caller id name" transfer/display between ISDN 
(Siemens PBX) and IP phone connected to asterisk
I'm using PRI interface and Q.SIG signaling.
thank you
