LOCAL NUMBERS

Why Does Area Code Matter?

A local phone number provides several significant benefits to a small business. Firstly, it enhances the company's presence in the local community and makes it appear more accessible to customers.

This local presence further establishes trust and credibility, as customers generally feel more comfortable dealing with businesses they perceive as local. From a practical standpoint, a local number is also more convenient and often cheaper for customers to call compared to long-distance or toll-free numbers.

Additionally, a local number serves as an effective marketing tool, reinforcing the association of your business with the local community. Lastly, having a separate business number helps maintain the privacy of your personal number, creating a clear boundary between professional and personal communications.

How to Spot a Spam Call or Text

Beware of unknown senders, urgent action requests, and too-good-to-be-true offers. Check for spelling errors and unfamiliar URLs. When in doubt, don't click or reply. Always verify from official sources.

Check for unknown numbers

Check for Unknown, Unfamiliar Numbers

A common sign of a spam call or text message is that it comes from an unknown or unfamiliar number.

Sometimes, these numbers may even appear to be from another country. If you don't recognize the number, be cautious.

Don't answer calls or reply to texts from numbers you don't know, especially if they aren't leaving messages.

Beware of too good offers

Beware of Too Good To Be True Offers

Spam messages often contain offers that seem too good to be true.

These could be promises of free vacations, big discounts, or large monetary rewards. As a rule of thumb, if something seems too good to be true, it probably is.

Always verify such offers from a reliable source before responding.

Look out for personal information requests

Look Out for Urgent Requests for Personal Information

Spam callers or texters often try to create a sense of urgency to get you to provide personal information.

They might pretend to be from your bank or a government agency, claiming there's a problem with your account or that you owe money. Never provide personal information in response to an unsolicited call or text message. When in doubt, hang up and contact the entity directly using a number you trust.

I was with another voip company for a few years. It was a disaster. I finally found VOIPLY and signed on. After being with VOIPLY for more than two years, I am thrilled to say that it is wonderful to speak to a human for great customer service. I get international calling free to most countries as well. They have great plans to suit everyone.

They are great company in that they try very hard but they still have some things to learn like when a customer ask for an instruction manual so they would know how to use the mobile app and the portal and all the other stuff the phone the system over 9 times and I still have not gotten the owners manual or any way to figure it out on my own. I finally used the portal instead of the mobile app today and it was like a miracle. It changed everything. I thought I was dumb or my phone was broken because nothing was working very well on the mobile app. When I got over to the portal everything worked fantastically. Voiply is fantastic. I was paying $10 a month with Xfinity and $240 on top of that to have TV service and a landline or VoIP. So you offer the phone for like $16 and all the other companies wanted $40 for a phone. So you guys are about the best deal in the market. It took a while to get the phone to work properly because it was getting ported over and so forth but I understand that. And then once it was working it's been fantastic I really love it. I got rid of Xfinity and I gained a good partner in voiply! I'm still loving the voiply service. I request today owners manual and they sent it to me right away. My new puppy loves it too!

We switched to Voiply after our current VOIP provider increased our rates 60% without warning (and we had been with them for over a decade). What a difference! They helped immediately with porting issues then fixed the mobile app so that we could get incoming calls. We were up and running within a day of the port completion. Our previous VOIP provider took days to fix an issue - Voiply fixed problems within minutes of our report. So customer support definitely gets five stars from us! The Voiply price is also more reasonable so that was very helpful. And both the web interface and mobile app were well written (I'm a software consultant/developer). I've added a picture of the Grandstream device that Voiply supplies for free. Besides power, it has inputs for a phone (RJ11) and an ethernet connection (RJ45). It is programmed to get a DHCP address on your internal network so be sure to allot some addressed on your firewall router for DHCP. We are glad that we ported to Voiply - what a difference from our previous supplier.
