MicroSIP Softphone

---title: MicroSIP Softphoneslug: /guides/microsip-softphonesidebar_position: 8x-custom: ported_from_readme: true---### OverviewIn this guide we will register a SIP endpoint to our MicroSIP Softphone. MicroSIP is an open-source, lightweight SIP client that works perfectly with SignalWire SIP endpoints.### What Do I Need?1. SignalWire account (guide [here](/guides/signing-up-for-a-space))2. Purchased or Verified phone-number in your SignalWire space (guide [here](guides/numbers-api/getting-started/buying-a-phone-number/index.mdx))3. Softphone client of your choosing. For this guide, we will use [MicroSIP](https://www.microsip.org/).### SignalWire SetupTo get started making calls, we will need to purchase a phone number and create a SignalWire SIP endpoint.#### Purchase a Number1. First, we will need to purchase a phone number with SignalWire. This can be done by navigating to your SignalWire dashboard, and clicking the Phone Numbers tab on the left-hand nav-bar.2. Select Get a Phone Number, or the +New button.3. Use SignalWires filtering features to select a number that suits your needs, and click the Buy button.4. Optionally, set a Friendly Name for the purchased number. This will make it easier to keep track of your numbers as you add more to your space.For more information on purchasing a phone number, check out our detailed guide ( [here](guides/numbers-api/getting-started/buying-a-phone-number/index.mdx) )#### Create a SIP endpointNow that we have our Phone Number, we can create our SIP endpoint. This endpoint will allow us to connect to a Softphone, and make outbound calls using our newly acquired number.1. Navigate to your SignalWire dashboard, and select SIP from the left-hand nav-bar.2. Click the Create a New Endpoint button.3. Select a Username and Password for your endpoint. These credentials are how you will connect your SIP endpoint to your Softphone.4. Select the desired phone number you would like to set as your Caller ID. This can be any purchased or verified number in your SignalWire space.5. Optionally, configure your codec and encryption settings. If you are not sure, it is suggested to leave them as their default settings.For more information on creating a SIP endpoint, check out our detailed guide ( [here](/guides/set-up-a-signalwire-phone-number-with-a-sip-endpoint) )#### Connect SIP endpoint to SignalWire Phone NumberIn the last step, we configured our SIP endpoint to call out using our Caller ID, but if a customer tried to call this number back, it would not reach the SIP endpoint. To ensure returned calls reach our SIP endpoint:1. Navigate to your SignalWire dashboard, and select Phone Numbers from the left-hand nav-bar.2. Select the Phone Number used, and click the Edit button.3. In the Accept Incoming Calls As drop-down menu, ensure it is set to \Voice Calls.4. In the Handle Calls Using drop-down menu, select SIP Endpoint.5. Use the drop-down/search feature to find the enpoint you created earlier. This will be the Username you set for your endpoint.6. Finally, select the Save button to save your changes.### MicroSIP Setup#### Download and Install1. Navigate to and install MicroSIP or MicroSIP Lite depending on the features you need. If you just plan on using this for Voice calls, either client will work!#### Register Your Endpoint1. Launch the MicroSIP client2. Select Add Account from the top-right drop-down menu3. Account Name is similar to the Friendly Name for our phone number, and is only to help keep track of several endpoints.4. SIP Server and domain should be set to your SignalWire SIP domain.:::cautionWhere is my SignalWire SIP Domain?:::

5. Username should be the username of your SIP endpoint.6. Domain should be the same as your SIP Server7. Login and Password will be your endpoint Username and Password:::infoVisual Reference:::

:::danger Security-Minded?:::8. Optionally, configure your encryption settings. If your endpoint requires encryption, set Media Encryption to Mandatory SRTP, and Transport to TLS.With this set, you can return to your SignalWire Dashboard, and set Encryption to Required.

:::tip Finished!You should now be able to handle inbound and outbound calling from your SIP endpoint using MicroSIP.:::### Try it YourselfIf you would like to test this example out, you can create a SignalWire account and space [here](https://id.signalwire.com/signup/account/new).Please feel free to reach out to us on our [Community Slack](https://signalwire.community/) or create a Support ticket if you need guidance!
