I have a few Verizon customers with PBXs experiencing one way speech. No incoming speech. These are incoming calls and it is not consistent but it is troubling for a medical office. Patients call the office, staff don't hear anything and hang up. Outgoing is fine. Happens often and the customer will call repeatedly and then both sides can speak. These are different systems, totally unrelated. Geographically they are in close proximity. I tested with land lines, cell phones and unable to recreate. But I've witnessed and answered incoming calls at these locations with no incoming speech. The problem is real. Typically it is the main number. I suspect it's almost always a cell phone calling but can't be certain.

I contact Verizon and plead our case. Haven't gotten very much of an answer, they suggest reboot the Fios ONT but these aren't all FIOS! Not sure how to proceed.

A few years ago I had a similar issue with Comcast and Verizon wireless. A Comcast tech described it as ghost calls and revealed they had a routing issue. Verizon so far hasn't admitted anything and I am curious if anyone else has had this problem.

How is the dial tone delivered? Actual POTS on the Verizon terminal? Copper or fiber circuit into an IAD to provide dial tone? If anything other than real copper POTS, it is probably the SIP backhaul from the premise to the CO.

Nothing is SIP or from an IAD. Some are POTS, standard copper from the street and some are Fios (fiber ont to copper).

I've learned some were POTs (standard) but have been converted to Multi Dwelling Unit Fios.
Which must be someplace in the building, unknown to us.

I guess we'll have to be persistent with Verizon to troubleshoot.

Is the Dial Tone coming in from a Mux or SLC? Maybe a remote off a CO? A problem with a card in one of those units could be causing your troubles.

Given that outgoing calls are consistently fine, but, incoming calls are hit or miss, I'm wondering if there is an issue unrelated to the customers. ponder

Specifically, if the originating callers are all using a CLEC as their service provider. This could point to a carrier problem between the CLEC and Verizon.

And the problem is gone. I called around and everyone is doing ok. Probably a Verizon issue that needed attention. I am cautiously optimistic.

Probably a problem in a CO somewhere that got fixed behind the scenes and IF anyone who fixed knew about the problem they won't release that information.
