Who helps resolve these issues?
Is Ooma really worth having if no one fixes these problems?
Simple problems, front-line support can handle. More difficult ones that involve back-end configuration, front-line support usually escalates, sometimes to an engineer.
Until you reach 2nd level support, don't take it personal. Almost all companies have this type of structure these days.
I think front-line support should be able to handle dropped calls and unable to dial out problems. Voicemail maybe. Caller-ID, they probably have to escalate.
If all else fails, you can try contacting ntoy or Bobby B, but personally I think you have a lot of problems and it would be best to wittle that down first.
Dropped calls is usually (but not always) a problem with reliability of your Internet connection, which can include router and/or cable modem issues.
Unable to dial out is usually (but not always) a problem with setup.
Call waiting with caller id, there were some problems before with certain brands and they put in a partial fix. Search the forums for CWCID
Unclear what the specific problem with Voicemail or Caller ID is, but probably those are back-end configuration issues that are best handled by escalation.
