BACKGROUND: NoMoRoBo is a service with a database of junk phone numbers.
It checks the caller ID number of your inbound call against their database, and
if there's a match, NoMoRoBo answers the call after one ring, plays a brief
recording, and hangs up, sparing the recipient from the junk call. The user
adds NoMoRoBo's number to a ring group (typically called "multi-ring" or
"simultaneous ringing" or something similar by various telephone providers).
---------------------------------------------------------------------------------------
I have NoMoRoBo on three VOIP.MS accounts: mine and those of two clients.
In spurts over the last month, NoMoRoBo has been answering calls from non-
junk numbers (family, friends) after 4 rings (instead of 1) and and playing
silence. This prevents an answering machine or Google Voice voicemail from
taking the call. When the problem is active, it happens to all three of us.
I've tested various VOIP.MS DIDs in various states. I've tried switching from
VOIP.MS's Dallas servers to their Houston servers. I've tried both of the
NoMoRoBo numbers that I know of, 202-729-9229 and 202-813-1600.
But none of these steps made a difference.
I haven't tried NoMoRoBo on other phone services such as Vonage, so I don't
know whether it happens there.
The problem might be at VOIP.MS, but I can't tell. No matter where the
problem originates, I suspect that it affects all VOIP.MS accounts that use
NoMoRoBo (including yours).
You might have a hard time duplicating the problem because it's sporadic.
If you'd like to see the problem, your best bet would be to add NoMoRoBo
to your VOIP.MS ring group, then occasionally check the VOIP.MS
printable call detail record (CDR) for indications that NoMoRoBo is taking
your calls inappropriately. Or you could wait until someone tells you,
"I called you, it rang a few times, then I got silence [or got cut off]".
Attached is an example of a defective call, from my VOIP.MS printable CDR.
Does any of you know why the problem occurs?
Has the problem been discussed elsewhere?
