I've just upgraded my SPA3102 from 5.2.10 to 5.2.13 to fix the VoIP doesn't work after a PSTN call problem and it has broken my Caller ID which is used for a Bellcore type PSTN line connecting to a UK set of phones.
Reverting the firmware to 5.2.7 fixed the caller ID without anything else being changed. Will have to see whether it cures the VoIP problem too without unleashing the PSTN echo which I've almost tamed.
