What is Call Forwarding or Call Routing?

Calls to your virtual phone number can be forwarded/routed to any phone number in the world, softphone or SIP device. We support simultaneous and sequential ringing.

  • Simultaneous ringing forwards calls to multiple phone at the same time. When the call is answered by one phone, ringing on all other phones stops.
  • Sequential ringing forwards a call to different phones in a timed order. For example, you might set up call forwarding to ring your office phone for up to 24 seconds, then your mobile phone up to 30 seconds, and then your home phone. If no phones answer, the call may be sent to voicemail or forwarded to a call center.
  • You can combine simultaneous and sequential ringing together. For instance, you could set up a group of three phones to ring simultaneously, then another three phones to ring, then another three phones.

Do You Support Interactive Voice Response (IVR)?

This feature is also referred to as an automated attendant, voice menu, or phone tree. You can set up custom voice menus that recognize key inputs or DTMF tones. Using an IVR, callers can be redirected to the proper person, extension or department. For example, an IVR may prompt callers to: "Press 1 for Sales Press 2 for Technical Support."

How Does Call Scheduling Work?

Call Scheduling allows you to route your incoming calls based on a calendar. You can schedule your calls based on the day, time or month. For example, you may schedule your calls to be answered by your agents from 9-6pm Monday through Friday. However, during the winter holiday season, you may have different hours and may even have your agents answer calls on the weekends.

What is Click to Call?

Click to Call allows visitors to your website to place a call using their browser. Our service will generate HTML code that you can place on your website, allowing your visitors to click a button and have their calls instantly forwarded to any phone number, smartphone or SIP device. No coding experience is required. Web calls answered by a Softphone will display caller location, browser & OS, web page location and caller’s local time. Optionally, you can prompt the caller to enter their name, phone number and email address before placing the call.

Can I Place Outbound Calls Using My Virtual Number?

Using our Softphone, you can place calls from anywhere you have Internet access. All calls are placed over the Internet and usage is charged to your SecondLine.com account. Your callers will see your virtual number as the caller id.
