Guide · Call Filtering and Spam
The call filtering service checks the calls on the lines you added: an incoming call by the caller's number, and an outgoing call by the number dialed. The check is made against the list of numbers kept by the Rabbinical Committee and against your personal block list, and callers who behave like spam are blocked automatically. In this guide: what the service does, where the screen is and what you see on it, how to join — with the whole PBX or with individual lines — and how much it costs, personal blocks, checking a number with the Rabbinical Committee, reporting a number, spam filtering, blocked calls, releasing a number, and who is allowed to do what.
The service follows the calls on the lines you added while they are in progress — it scans the live calls on the PBX every second and a half — and checks each call in three ways:
The call doesn't go on to its usual destination: the service sends it to a block destination set in advance, such as a recorded message. The same goes for an outgoing call — someone who dials a blocked number reaches the block destination, not the number they dialed. Every blocked call appears on the screen, with the reason (step 10).
In the control panel, in the side menu, under Call Management — Call filtering. The screen is open to all users on the account; what each one can change depends on their role and permissions (step 12).
At the top of the screen there is a short row of figures:
| Metric | What it tells you |
|---|---|
| What is filtered | "The whole PBX", the number of lines added (for example "3 lines"), or "Not in the service". |
| per month | The monthly charge for the service, in shekels (₪) + VAT. Shown after you join. |
| Calls blocked today | How many calls were blocked on the account today. |
| Blocked this month | How many calls were blocked since the start of the month. |
Below the row are the screen's cards:
In the lists on the screen — the lines, the numbers you blocked and the blocked calls — you can search, sort and filter by column, and choose a table view or a card view.
In the editor of every extension, number and code there is a section called Call filtering service, with the "Call filtering on this line" switch (On / Off). This way you can add a line to the service, or remove it, from the editor too. When the whole PBX is in the service, it says there that calls on this line are checked too, and there is no switch.
There are two ways to join:
| Method | What is filtered | Who can add it |
|---|---|---|
| The whole PBX | All of the account's calls — incoming and outgoing, on every extension, number and code, including lines added later. | The system owner, a reseller or a manager |
| Individual lines | Only the calls that pass through the extension, number or code you added (step 4). | Any user, for lines they have permission to edit |
Individual lines you already added are included in the whole-PBX price.
The first time you join, the confirmation question includes the explanation "Before you join — what the service does with the calls": the system follows the calls on the lines in the service and checks them; Kesher may record calls from time to time, to test the filtering and the spam detection — the recordings are checked by computer only, and no person listens to a customer's recordings; identifying details and sensitive information are deleted, and the information is not sold or given to others; and you can always remove the account from the service and ask for the data to be deleted. Check "I have read this and I agree, as set out in the terms of use and the privacy policy", and only then does the add button become available.
When the wording of the terms is updated, an account that is already in the service sees the Accept the terms of service card at the top of the screen, and accepts again. The terms are accepted by whoever can add lines to the service.
When the whole PBX is in the service, the card shows the Remove the PBX from Filtering button (only for the system owner, a reseller or a manager). Individual lines that were added before that stay filtered on their own. You remove a single line with the "Remove from Filtering" button in its row (step 4).
You don't have to filter everything. The Individual lines card lists all the extensions, numbers and codes on the account, and for each one:
| Column | What it includes |
|---|---|
| Type | Extension, number or code. |
| Name | The line's description in the PBX. A line that was added and later deleted from the PBX is marked "Not found in the PBX", and you can only remove it from filtering. |
| ID | The extension number, the number itself, or the code. |
| Filtering | "Filtered" or "Not filtered"; when the whole account is in the service — "The whole PBX". |
| Since | When the line was added, and who added it. |
| Actions | Add to filtering, or remove from it. |
Above the table there is a Search lines field (by name or number, even without dashes), a status line such as "2 of 15 lines filtered", and the price per line.
You can do the same from the line's editor: in the Call filtering service section, click the "Call filtering on this line" switch, and confirm.
The service identifies the line you added and checks only the calls that pass through it. A call that doesn't pass through any line you added goes on as usual.
On the Blocking numbers card, under Personal block list, you block numbers only for your account — on all the lines in the service, for incoming calls and for outgoing calls too. The block doesn't affect other customers. It works after you join the service, with the whole PBX or with at least one line.
Is the number spam? Before blocking, check the box "This is spam — also send it for the service manager to check" (step 9).
Want to know if a specific number is blocked by the Rabbinical Committee? The Blocking numbers card has the section Check a number with the Rabbinical Committee. The check is available to anyone who can see the screen, even before joining the service.
When the number is open, on an account that is already in the service, the Report This Number button appears below the answer. Clicking it opens the report form with the number already filled in, and the cursor in the "What kind of number is it" field: write the reason for the report there, and send it (step 7).
A problematic content line, or a number not suitable for the Haredi public? On an account in the service, you report it from the Blocking numbers card, and the service manager decides what to do.
| Field | What to write |
|---|---|
| Number | The number you're reporting. In a report from the committee check, it's already filled in. |
| What kind of number is it | The reason for the report: what is on this number, and why it isn't suitable. Up to 500 characters. |
| Your phone | If we have your mobile number on file, it is suggested in advance, and you can change it. If the report is passed on to the Rabbinical Committee, it is sent with this phone number. |
| Block the number for us right away too | Optional. Check it so the number is blocked for you right away, without waiting for a decision. |
The service manager checks every report and decides: pass it on to the Rabbinical Committee, block it for all subscribers to the service, or reject it. In the This account's reports list, which all users on the account can see, each report appears with its status:
| Status | What it tells you |
|---|---|
| Awaiting decision | The service manager hasn't decided yet. |
| Sent to the Rabbinical Committee | The report was sent to the committee, and the decision whether to block is theirs. |
| Blocked for all subscribers | The service manager blocked the number in the service, for everyone who joined. |
| Rejected | The number won't be blocked because of the report. |
Next to each report you also see the time, who reported it, and "Blocked for your account" if you chose to block the number right away.
Spam filtering works for everyone who joined the service, with no setup needed, and it checks incoming calls only. Here's how it works:
Got a spam call? You can mark the number yourself, in two ways:
What happens after marking:
Marking works after you join the service. A read-only user doesn't see the link.
The Blocked calls card shows every call blocked on the account in the last 7 days. The row of figures at the top of the screen shows how many calls were blocked today, and how many since the start of the month.
| Column | What it includes |
|---|---|
| When | The date and time of the call. |
| Number | For an incoming call — who called; for an outgoing call — the number dialed. |
| Direction | Incoming or outgoing. |
| Cause | Why the call was blocked (see the next table). |
| Cause | What it means |
|---|---|
| Rabbinical Committee | The number is on the committee's list. |
| Personal block list | The number is on the list of numbers you blocked. |
| Spam (temporary block) | The number was blocked for an hour by spam filtering. |
| Spam | The number was blocked permanently by spam filtering. |
| Blocked by the service manager | The service manager blocked the number for everyone who joined, for example after a report. |
You can search, sort and filter by direction or by reason. If no call was blocked in the last week, it says "No calls were blocked in the last 7 days".
What to do depends on the reason shown in "Blocked calls":
| Reason | How to release it |
|---|---|
| Personal block list | Yourself: Remove next to the number in the "Numbers you blocked" list (step 5). |
| Spam (temporary block) | The block ends on its own after an hour. The service manager can also release it sooner. |
| Spam; Blocked by the service manager | The service manager releases it. They can also set a number as protected, so it won't be blocked as spam in the future. |
| Rabbinical Committee | The decision belongs to the committee, and the number can't be released from the screen. |
Think a number that matters to you was blocked? Write to us through the Contact Us page or through Report a Problem, with the number and the time someone tried to call.
| Who | What they can do |
|---|---|
| The system owner, a reseller or a manager | The role in the PBX. Adds and removes the whole PBX, and also any individual line. |
| Another user on the account | Adds and removes only extensions, numbers and codes they have permission to edit. |
| Any user who isn't read-only | On an account in the service: blocks and removes numbers in the personal block list, reports a number, and marks a number as spam. |
| Read-only user | Sees the screen and checks a number with the Rabbinical Committee, but doesn't change anything. |
| Service manager | On behalf of Kesher. Decides on reports (passing them on to the Rabbinical Committee, blocking for all subscribers, or rejecting), decides on numbers suspected of spam (a permanent block for everyone, or release), releases a number blocked by mistake, and sets protected numbers that aren't blocked as spam. |
| Rabbinical Committee | Keeps the list of numbers that the service checks every call against. |
