Caller ID on analog phones

[CarlosPrex]

Customer has an early Definity R9.5

Since It´s a Hotel, they have PMS working fine, but now all they need is two analog phones could recieve Caller ID when any room call for service.
Ports are located on TN793B analog board, Caller ID type assigned, and Protocol for Caller ID Analog Terminals is Bellcore.
Problem is when any adminitrative station (digital) calls caller id info is shown correctly, by when a room calls info of Caller ID is not displayed.

...now I noticed that if Client Room is y in COS, caller id from calling room is not displayed, if Client Room is n, info works fine.
I´m aware system is old and one solution is move those stations to a digital board and install digital phones, but customer is hoping there´s a solution, since more stations will need to recieve caller id soon.

Any suggestion ?
Thanks in advance

I don't know the Definity system well, but I will note you can get refurbished 6400 series phones for around $40 each and a 16 or 24 port digital card for between $30 and $40.

On the station, is the phone type set to callerid? If so, then by design, guest room to guest room callerid is blocked. Non-guest room to guest room callerid should be shown. Callerid from outside calls transferred or DID calls to the rooms should also display.
