RingEX
</div></var> integrations, your agents will connect to their calls using the same industry-leading telephone service as the core <var class="keyword">
<div style="display: inline;">
RingEX
</div></var>. This means your agents can expect exceptionally high call quality with class-leading reliability on the agent-leg connection, all using the same browser-based and fully integrated softphone you've come to enjoy. Your agents can also sign in with external <var class="keyword">

Phone number management
-----------------------

With <var class="keyword">
<div style="display: inline;">
RingEX
</div></var> integrations, all <var class="keyword">
<div style="display: inline;">
RingCX
</div></var> customers have access to self-service phone number management. Using the <var class="keyword">
<div style="display: inline;">
RingEX
</div></var> service portal, you can order any amount of toll-free phone numbers or local DIDs in the location(s) of your choosing, and they become immediately available. When you are finished with a number and no longer need it, simply cancel it within the same self-service portal and you won't be charged again. For more information and instructions on how to purchase numbers and configure them to route to <var class="keyword">
<div style="display: inline;">
RingCX
</div></var>, go to [Purchasing phone numbers in <var class="keyword">
<div style="display: inline;">
RingEX
</div></var>.](https://support.ringcentral.com/article-v2/Purchasing-phone-numbers-in-RingCentral-Office.html?brand=RingCentral&product=RingCX&language=en_US "")

Once you have purchased a toll-free number or local DID, it must be imported into your <var class="keyword">
<div style="display: inline;">
RingCX
</div></var> account and assigned to its final destination, typically an IVR or directly to an inbound ACD queue. For more information, see [Configuring the CCRN in <var class="keyword">
<div style="display: inline;">

User management
---------------

With the convenience of <var class="keyword">
<div style="display: inline;">
RingEX
</div></var>, you manage your agents and back-office workers from a single location. By creating free "virtual extension" users, you may add an unlimited number of extensions to your system for use as a typical <var class="keyword">
<div style="display: inline;">
RingCX
</div></var> agent. For the case of users who require both back-office and <var class="keyword">
<div style="display: inline;">
RingCX
</div></var> agent availability, you can create paid-for "digital line" users, which expose additional features such as external physical device connectivity and direct inbound phone numbers. In either case, these users can be imported or linked into <var class="keyword">
<div style="display: inline;">
RingCX
</div></var> as agents, supervisors, and/or administrators, and are able to log in with a single set of credentials. To get started adding new users to your <var class="keyword">
<div style="display: inline;">
RingCentral
</div></var> account, see [Add a User Extension Without an Assigned Phone](https://support.ringcentral.com/article-v2/Adding-user-extensions-in-the-RingCentral-app-and-Admin-Portal.html?brand=RingCentral&product=RingEX&language=en_US "").

After you have one or more users created within <var class="keyword">
<div style="display: inline;">
RingEX
</div></var>, you then [Import an agent from <var class="keyword">
<div style="display: inline;">
RingEX
</div></var> into <var class="keyword">
<div style="display: inline;">
RingCX
</div></var>](https://support.ringcentral.com/article-v2/Creating-an-agent-in-RingCX.html?brand=RingCentral&product=RingCX&language=en_US ""). Once imported, you can read more about [how to configure your agent](https://support.ringcentral.com/article-v2/Intro-to-agent-configuration-in-RingCX.html?brand=RingCentral&product=RingCX&language=en_US "").

Once the agent is created in <var class="keyword">
<div style="display: inline;">
RingEX
</div></var>, imported to <var class="keyword">
<div style="display: inline;">
RingCX
</div></var>, and properly configured, all that remains is for the agent to log in and get connected. For more on this, see [Logging in to the platform](https://support.ringcentral.com/article-v2/Signing-in-to-RingCentral.html?brand=RingCentral&product=RingEX&language=en_US#pills-nav=ringcx "").

For administrators, the process is a little different. You first [create an administrator](https://support.ringcentral.com/article-v2/Adding-an-admin-user-in-RingCX.html?brand=RingCentral&product=RingCX&language=en_US "") in <var class="keyword">
<div style="display: inline;">
RingCX
</div></var> and then link the administrator to an existing <var class="keyword">
<div style="display: inline;">
RingEX
</div></var> user. This provides the ability for all users to sign in with the same <var class="keyword">
<div style="display: inline;">
RingCentral
</div></var> credentials regardless of their role or user type. For more information on how to sync an administrator or agent with an existing <var class="keyword">
<div style="display: inline;">
RingEX
</div></var> user, see [Syncing users from <var class="keyword">
<div style="display: inline;">
RingEX
</div></var>](https://support.ringcentral.com/article-v2/Creating-an-agent-in-RingCX.html?brand=RingCentral&product=RingCX&language=en_US "").
