Pros

“Routine tasks — sending a multi-page fax, copying a configuration — turn into multi-hour or multi-day ordeals. If your workflow depends on faxing or on managing your own phone configuration, look elsewhere before you commit.”

Chris G.

Owner

“I explained that I was sold the account with the understanding that all 5 of my phone numbers could use SMS at the same time.”

Bob W.

owner

“The ability to call customers from the app where my personal cell phone number will not show up.”

Amy L.

Office Manager

Pros

“We have around 300 phones deployed with Asterisk / FreePBX and when comparing the costs against industry leading phone solutions we are saving tens of thousands of pounds per year.”

Nathan T.

Network Infrastructure Manager

“it's very cost effective and that's why I believe it's a top tier solution you should consider for any size of business.”

Nathan T.

Network Infrastructure Manager

“This is my go-to choice for larger deployments but a packaged version with extras and IT support staff are both necessary for successful deployments.”

Tim M.

IT consultant

Cons

“I contacted support (each time I spent time with the AI agent and frustrated, would give up, ask for a live agent and be on hold for some time.”

Bob W.

owner

“Literally 20+ emails to close my account and they still charged my credit.card the momth after i closed my account.”

Jason S.

President

“However, despite this, Nextiva continued charging our credit card for five additional months, without our authorization.”

Joseph S.

HR Adminstrator

Cons

“It entails a number of severe security threats. and We don't obtain the complete event of Outdial parameters in the Asterisk manager interface layer.”

Osama A.

“Documentation is not good enough. When you have some problem it is hard to find the solution. If you do not secure the server, huge phone traffic can pass through your server.”
