Alcatel Unleashed

I have a omniPCX office medium own licences of all digital, ip and analog phone.
The external access is isdn T2

I call from outside to ip or digital numbers, it get caller id as nomal
But when i call from outside to analog numbers, my analog phone can not get the caller id.
I tested the checked or unchecked the "clip is diverted party" in extension detail board -> features but it had no effect
My analog phone can get caller id with the external analog public line.

May i miss config my pbx ?
anyone can help me correct this problem

thanks in advance

This is an OXO question please post in right section. Guys, don't approve this kind of posts.

Moved for obvious reasons.

Is your analog extension configured as Z class?

Try to change in OMC type of analog set from Z set(Normal) to Z set (Class).
