Verizon Call Filter blocks some EC500 / X-Mobile forwarded calls 1

[Winky92]

Just a heads up in case anyone is using EC500/X-Mobile to send calls to Verizon smartphones...

Apparently, Verizon has been, without consent and as a public service, installing 'Call Filter Plus' on many smartphones. This feature quietly blocks EC500 forwarded calls if the originating number does not conform to a standard PSTN numbering format.

I've been using EC500 quite a bit to work from home (seems to be a trend lately), and I've setup a bunch of users with that feature in the past couple months.
On perusing my 'Recent Calls' log on my phone, I saw quite a few incoming calls marked as 'Blocked - High Risk'. These were all 4-digit extensions forwarded via EC500. My phone wasn't giving me a peep or a notification about them, so I had no idea I was missing so many calls. The culprit turned out to be that 'Call Filter Plus' App. Once I opened this app on the phone and switched OFF the option to 'Block Spam Calls', my EC500 sent all calls without issue.

I was still receiving calls from extensions that had a 10 digit DID public number assigned, but all the regular 4 digit internal extensions were blocked. Perhaps Verizon meant well (?), but it has screwed me over.

Yup. Canada did something similar - if it's not a legit 10 digit CLID, carriers must block.

Not that scams call from a 4 digit extension ever, so it only ever bugs us.

Fix your public tables and stuff.

public unknown is your fix so you dont send bad CLID to the PSTN.

Similar Tmobile has a spam blocker which will block even good 10 digit numbers which are valid numbers. For some reason if you get on their list you wont be able to call any Tmobile user. The fix is to log your numbers with this company and they will get you white listed.
