Straight answers to the questions Los Angeles businesses ask most about switching to a cloud phone system with Supreme Call: pricing, contracts, keeping your numbers, equipment and support.
Plans run $19.99 to $24.99 per extension per month. The price depends on the features each extension needs. There is no installation fee, and phones, numbers and add-ons are quoted up front during a free consultation.
No. Supreme Call does not charge an installation fee. A technician configures your system, installs the phones on-site in the Los Angeles area, and trains your team as part of the service.
No. Service is month-to-month. You can cancel with 30 days’ notice, so you are not locked into a multi-year agreement the way many traditional phone contracts work.
No. Like all phone providers, Supreme Call bills applicable taxes and regulatory fees separately. They vary by location and are shown on your quote and invoice.
Yes. Supreme Call can port your current numbers, including 310, 213, 818 and other Los Angeles area codes, from almost any carrier. Your numbers keep ringing on your old service until the port completes on a scheduled date.
Number porting usually takes one to three weeks, depending on your current carrier. Supreme Call can set up temporary numbers so you can start using the new system before the port finishes.
No. Your current service stays active until the port date. On that day calls start ringing on the new system, usually within hours, and the team stays on hand to confirm everything works.
Yes. Supreme Call provides new local numbers in Los Angeles area codes, toll-free numbers, and international numbers, so you can add a line for a new location or a marketing campaign.
A cloud phone system, also called VoIP or cloud PBX, runs your business phone lines over the internet instead of copper phone lines. The phone system lives in a secure data center, so you need no PBX hardware in your office.
You need an internet connection and phones. Supreme Call supplies and configures Yealink and other business desk phones, cordless phones and conference phones. Staff can also use the free mobile and desktop apps instead of, or alongside, a desk phone.
Yes. The Supreme Call mobile app rings your business extension on your smartphone. You can answer, transfer and make calls showing the business number, and send business text messages, without giving out your personal cell number.
Each active call uses about 100 kbps in each direction, so most business internet plans handle many calls at once. Supreme Call checks your network before installation and adjusts your router settings for call quality.
Calls can automatically forward to cell phones or another number, and voicemail keeps working in the cloud. Supreme Call also offers automatic failover to a 4G or 5G backup connection, so desk phones stay up during an outage.
Yes. Business VoIP phones can call 911. Federal rules require a dispatchable location for each call, so your service address is registered during setup. Tell Supreme Call when an office moves so the 911 address stays correct.
An auto attendant is the automated greeting that answers calls and routes callers, for example “press 1 for sales.” It can send calls to people, departments, voicemail or after-hours messages, 24 hours a day.
Yes. Voicemails can be delivered to your email as audio files, and also as text transcripts, so you can read a message in seconds and reply from anywhere.
Yes. Supreme Call offers online fax. Incoming faxes arrive in your email, and you can send faxes from your computer, which replaces the fax machine and its dedicated phone line.
Yes. Call recording is available for training, quality and record-keeping. Recording laws vary, and California generally requires all parties to consent, so callers should be notified.
Yes. Business texting lets your team send and receive SMS from the business number through the mobile and desktop apps. Business texting requires carrier registration, and Supreme Call guides you through it.
Carriers label calls based on calling patterns and number reputation. Supreme Call helps register your numbers and sign calls properly so they display correctly. See our guide to why business calls show up as Spam Likely.
