Can anybody tell me what standard the caller ID uses on the HG659 as I can not get any numbers displaying on incoming calls. When using a linksys PAP 2 it will display incoming numbers but only if using ETSI FSK or ETSI FSK with PR setting and my phone is a V-Tech 20-2431. Have tried with CLIP enabled and unticked as well. Is there a way to change the setting with the HG659.
Please don't tell me that this phone is not compatable as I have it because it is a 2 line unit as I also have a UK landline number.
