Phone Power vs CrazyCall

I have been a customer since 2009. The service meets my needs with the main line and a cloned line, giving me the ability to have 2 calls simultaneously. From the beginning I have brought my own adapter (picking it from the list of supported devices). I recently replaced it and discovered that the automated provisioning scripts don't support the setup of the second line. That's okay -- I contacted PhonePower and they put me in touch with one of their technicians who was able to give me enough information so I could manually configure my adapter. Recently (August 2023), I noticed that my adapter showed everything was good but calls weren't coming through (going immediately to voicemail) and then one of the 2 lines became inactive. I contacted support via email and continued to work on the problem (I'm in IT so I don't mind digging into problems and stepping through a reconfiguration process). Using my notes from the manual setup, I got things working again. I also noticed that my firmware on my adapter was significantly out of date and updated it too. I had it fixed before customer support reached out to assist. Things ran well for a number of weeks and then suddenly calls were going directly to voicemail again. That's actually not a bad thing since PhonePower automatically sends a copy of the voice mail to my email. So, I typically screen my calls anyway. To fix it, I have simply unplugged my adapter for a few minutes and then everything works fine -- I can call the house phone from my mobile and everything rings through just fine. I don't know if this is a problem at PhonePower or with my adapter or perhaps my internet provider. I'll dig into it one of these days but it isn't on the top of my list to fix. The amount of spam calls has been reduced by use of NoMoRobo which Phone Power provides free along with good instructions to setup. So, overall, I'm happy with PhonePower. The sound of the calls is excellent; customer service has been responsive and helpful; and it does a pretty good job filtering out spam calls. Some reviewers have reported caller id not working in the past. All I can say is that it has always worked for me since 2009.
