# Connect your own number to the CRM: another carrier's number via SIP

Your familiar business number stays with your carrier, and calls go into the incoming scheme and the CRM: fields, statuses, a softphone test and limits.

> **In short:** You can connect your own number to the CRM via SIP: the number stays with your carrier, and incoming calls to it follow the account's scheme and create leads. Open “Telephony” → “Connect your number”, enter the number and the SIP data from your carrier, tick “I confirm this number belongs to me” and click “Save”.

It's worth connecting your own number to the CRM if it's already printed on business cards, signs and ads. Changing it is expensive, and losing calls to it costs even more. Once connected, calls to the familiar number are distributed between managers, land in the CRM and can go to a voice bot if you want.

A SIP number is a number that the carrier delivers over the internet through a SIP account: a login, a password and a server address. Your carrier provides this data, usually in its customer account. The number stays yours, and your contract with the carrier doesn't change.

Watch the 90-second video, and below you'll find the step-by-step connection.

## Why businesses need it

- A company with a well-known number: clients call from old business cards and ads, and not a single call is lost when you move to the CRM.
- A branch network: each branch has its own number, and in the incoming call scheme each number gets its own group and its own employees.
- Ads on your own number: you can give the number a type and a source, and calls from a newspaper or a banner land in the lead with that source.
- Switching without downtime: the number connects in a few minutes, and clients don't notice anything.

## How your own number works via SIP

The account registers with your carrier using the SIP data, like a regular SIP phone. An incoming call to the number goes to the “Incoming call” entry: into the “Other numbers” branch or into a group where you add the number. Then the scheme takes over — employees, schedule, voice menu, bot. How to set it up is covered in the article [cloud phone system for business](http://my.lptracker.ru/land/lk/faq/?a=inbound-scheme-start&format=md&lang=en).

In the “Numbers” list, such a number is labeled “Own telephony”, and the “Status” column shows “Connected”, “Not connected” or “Blocked”.

## How to connect a number from another carrier: step by step

1. **Get the SIP data** — In your carrier's customer account, find the SIP login, SIP password and SIP server address. Check the port and SIP proxy there too, if the carrier requires them.
2. **Open the window** — “Telephony” → “Connect your number”, or “Numbers” → “Add number” → “Connect your own number”.
3. **Set the project and provider** — The “Project” where the number will work, and your carrier in the “Provider” list.
4. **Enter the number** — “Number” and “Shown number”: how the number will appear in the account.
5. **Paste the SIP data** — “SIP login”, “SIP password”, “SIP server”. “Port” is 5060 by default; fill in “SIP proxy” only if it's needed.
6. **Choose the type** — “Online (dynamic)” with a “Source” for website substitution, or “Offline (static)” with an “Ad source name”, for example “newspaper”.
7. **Confirm and save** — The “I confirm this number belongs to me” checkbox → “Save”. You'll see “Number will be added shortly”.

## Why your own number is “Not connected” and what to do

Registration isn't instant. In the first seconds, the number may show “Not connected”: the list re-reads itself for about a minute and a half, and the status changes without reloading the page.

- “Connected” — registration succeeded, and the number takes calls.
- “Not connected” — there's no registration. Check the login, password, server, port and proxy via ⚙ → “Edit SIP data”.
- “Blocked” — the number is blocked. Delete it and connect it again with verified data, and if the status returns, contact support.

The easiest way to check SIP data is in a softphone. Enter it in Zoiper or MicroSIP and make a test call: if it fails there too, the data doesn't work, so ask your carrier for valid data. If the call works in the app but not in the account, contact support. How to fill in a softphone is covered in the article [SIP phone setup](http://my.lptracker.ru/land/lk/faq/?a=softphone-sip&format=md&lang=en).

## How your own number differs from your own PBX

Your own number takes incoming calls. You can't call clients from it through the built-in telephony: if you set it as employees' caller ID, outgoing calls won't go through, and the red bar “Outgoing calls from this number will not go through” appears above the “Numbers” list. Automatic number replacement doesn't apply to your own number either.

| What you need | What to connect |
| --- | --- |
| Take calls on your familiar number | “Your number” via SIP |
| Call clients through your own carrier | “Own telephony” |
| A number for outbound calls and a voice bot | Number rental in “Numbers” |

If outgoing calls should also go through your carrier, connect the whole PBX — this is [PBX CRM integration](http://my.lptracker.ru/land/lk/faq/?a=own-pbx&format=md&lang=en) in the “Own telephony” section. A number for calling clients is easier to rent: prices are in the article [virtual phone number for business](http://my.lptracker.ru/land/lk/faq/?a=phone-numbers&format=md&lang=en).

> Add your own number to a separate “Incoming call” group with the “+ number group” button if calls to it need different handling than other numbers. For example, the number on your sign goes to the receptionist, and the number from ads goes to sales.

## Frequently asked questions

### How do I connect my own number to the CRM?
“Telephony” → “Connect your number”, enter the number and the SIP data from your carrier, tick “I confirm this number belongs to me” and click “Save”. The “Connected” status means registration succeeded.

### Where do I get the SIP login, password and server for my own number?
Your carrier provides them, usually in its customer account. If they aren't there, ask the carrier's support.

### What if the status stays “Not connected”?
Check the login, password, server, port and proxy via “Edit SIP data”. Then enter the same data in a softphone: if the call fails there too, ask your carrier for working data.

### Can I call clients from my own number?
Not through the built-in telephony: outgoing calls from it won't go through. For outgoing calls through your carrier, connect “Own telephony”.

### Can I use my own number for call tracking?
Yes, choose the “Offline (static)” type with an “Ad source name” or “Online (dynamic)” with a “Source”. Calls to this number will land in leads with that source.

### How do I change my own number's SIP data?
⚙ next to the number labeled “Own telephony” → “Edit SIP data”. Enter the password only if it has changed.
