Displaying Caller ID on analog phones

Hi,

I just managed to get my Caller ID recognized by FreePBX/Asterisk. The system is now displaying
it now on incoming calls via an analog landline in the CDR records.
I have setup my system to forward in coming calls to my analog phone. It’s all working fine, but
they won’t display the transmitted CID. When I hook up my analog line directly to the phone and
I call from my mobile, it is displaying the CID fine / the name stored in the handset.
So when the handset is connected to FreePBX it won’t display the CID, only “Incoming call”. And (I am currently at work) the call history says “No number”.

I have tried
callerid=asreceived
cidsignalling=v23
cidstart=polarity
useincomingcalleridondahditransfer=yes
in chan_dahdi.conf but to no avail.

I have a Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface (rev 01) with one FXO and one FXS.
Landline is connected to the FXS and my analog phone is on FXO.
My analog phone is some DECT BT analog phone with two headsets.
I am based in the UK.
I just noticed a duplicate “callerid=” in dahdi-cannels.conf I have removed this now and rebooted. I can’t test this though as I am at work right now.

Any advise?

Regards

Thomas
