My callcentric VoIP phone stopped working yesterday, and it's still out.
I have a new ISP: they bought out the old local company which was providing cable TV and Internet service, and I've been having trouble ever since. Streaming media such as Reuters and CBS news have gaps in their audio feeds, and even missing video while the audio continues on, and the online Zoom video call I (and others) used yesterday to attend my Quaker meeting without risk of Covid-19 was so intermittent that I had to drop out and log back in twice.
The new Cable TV/ISP owner started their operations a few weeks ago. On the day they took control, I lost the ability to log in to the T-D servers at M.I.T. I had to install VPN software to regain access, and then when I tried to find out which North Carolina government agency regulates such companies, the TCP port which is used for "ssh" connections was suddenly not blocked anymore.
Yesterday, my VoIP phone went dead. It's a three line phone, and there are two VoIP services I use it for: Callcentric, where I get my "home" phone number, and the Hamshack Hotline, a free VoIP service for Amateur Radio operators like me. They both quit at the same time.
This morning, I talked to a person at the new cableco's "trouble" number, and she told me that she was going to reset my cable modem. Lo and behold, the Callcentric line came back, long enough for me to make a call to my sister's home in Massachusetts: I talked to my brother-in-law for a few minutes, and said 'goodbye,' and hanged up. A few minutes later, the line was out again.
I called the new cableco's trouble department again: they told me that it's a problem in my router and demanded that I call the company that made the router for help. I told them they were wrong, and demanded to speak to Tier 2 support, and they said they would submit a ticket but that the departement which handles that isn't open today.
This reminds me of what Comcast was caught doing a while back: they would block any port that they didn't like, and when anyone complained, they'd open the port for a few days, and then go back to blocking it again.
I'll call the new cableco tomorrow, and ask what it will cost to restore VoIP connectivity. Suggestions welcome.
