Business VoIP questions

Straight answers on numbers, phones, texting and call quality.

Still unsure? Talk to an engineer

Do you offer VoIP service outside the DC area?

Yes. Our managed VoIP service is available to businesses in all 50 states. Phones ship pre-configured, setup and training happen remotely, and our team supports every location the same way.

Can we keep our current phone numbers?

Yes. We port your main line, direct numbers and toll-free numbers. Most ports finish in one to three weeks, and we schedule the cutover so callers never hit a dead line.

How do the phones get set up if you are not local?

We program every desk phone before it ships, with your extensions, call routing and voicemail already in place. Your team plugs the phones into the network and they register on their own. Mobile and desktop apps are set up with a remote session.

Can we get local numbers in other states?

Yes. We can add local numbers in any U.S. area code, plus toll-free numbers, so you can show a local presence in each market you serve.

Can we text customers from our business number?

Yes. Business texting lets staff send and receive texts from your company number on desktop and mobile, so customer conversations stay with the business instead of on personal phones.

Do we still need desk phones?

Not always. Many teams use the mobile and desktop apps, which show your business caller ID. We set up desk phones for reception, front desks and anyone who is on the phone all day.

What happens if our internet goes down?

Calls follow backup rules we set ahead of time, such as forwarding to a cell phone or another office. The mobile app keeps working over cellular data.

How does E911 work with VoIP?

Every phone gets a registered address, so 911 calls reach the right local dispatch center with your location. Federal rules require this for business phone systems, and we update it when people or phones move.

Can calls be recorded?

Yes, for the lines and users you choose. Recording laws vary by state and some require every party to agree, so we set up a recording notice where you need one.

Is support available after hours?

Yes. VoIP support is available 24/7, and new users, number changes and call flow updates are handled by our team for you.
