CPU128 Version 9.0. Can't get the CALLER ID to pass to the handsets. Works fine on buttsets or other analog handsets of 16SLC. Using a 16SLC card with external power supply. CALLER ID works but not on DuraFon PRO, was asked to look at timers to extend CALLER ID but cant locate anything.
I find this strange but this is from the DuraFon troubleshooting guide: Caller ID not working (w/ external antenna)
Possible causes: Grounding of external antenna
Suggested remedies: verify Caller ID works when external antenna is
removed and rubber antenna used. If the Caller ID now works, the external
antenna should be grounded by its own separate ground in order to avoid the
building ground interference. If Caller ID does not work after replacing the
external antenna with the rubber antenna verify Caller ID service from phone
company to operational. If still fails contact EnGenius customer service at
