Pros and cons

We have utilized a number of providers and this provider is the most stable, responsive and reliable we have found.
The service level has been outstanding, availability being something we take for granted. Their customer service and support are refreshingly effective, which can be rare with traditional telecom.
Overall SIP.us has been great. I continue to do business with them because of the quality of the service.
Failures, issues and downtime: Too many to deal with for a service provider, lost VoIP clients due to Sip.us downtime that took too long to resolve.
But from my PoV as a customer, what I see is simply that Skype-made calls work where SIP-made calls are failing to go through. So what is Skype doing that SIP cannot.
The UX can be convoluted at times. Sometimes a person we had on backup phones ages ago will still get a call, and I have found it difficult to get him removed.

SIP.US solid services

Reviewed 4 years ago

My justification for using SIP.us was simple: better pricing than anyone with similar features/ratings. My justification for using SIP.us when expanding to ALL voip: value and 2 years of uninterrupted service.

Pros

SIP.US provides rock-solid VoIP trunks. We used them for our first VoIP PBX deployment and have literally had zero problems with them. Their reliability to provide consistent service is imperative as we're a heavy voice user.

Cons

I have no complaints or negative experiences with SIP.us

System Independent

Reviewed 4 years ago

We have a system that makes outbound calls via SIP. SIP.US gives us an independent communication separate from our corporate phone system.

Pros

The software provides real time reports. From time to time we receive complaints that a call didn't go through. We can pull a report and see if the went to the right phone number and if it was picked up.

Cons

Email notification with how many times all trunks are busy but it doesn't say when this happened.

Reviewed 4 years ago
Pros

Easy to use and setup. Customer service is great. Great team to work with.

Cons

Failures, issues and downtime: Too many to deal with for a service provider, lost VoIP clients due to Sip.us downtime that took too long to resolve. Cost of product is at a premium, yet quality of product is not.

Best Implementation!

Reviewed 4 years ago

SIP.US was a great find. I wanted to set up my own SIP trunk, run my own PBX, use my own IP phones. I thought the hardest part was going to be the SIP trunk. With SIP.US, it was actually the easiest part of the system to set up. Not one glitch, no surprises, and it is the most economical choice I could hope for.

Pros

Easy to set up, easy to use, easy to manage!

Cons

I have zero complaints! SIP.US was very easy to work with.

Impressive uptime and call quality

Reviewed 4 years ago

My initial concerns were primarily regarding uptime and call quality and neither have been an issue in close to 2 years now. I've had to reach out to the support department on occasion and pleasantly surprised by their knowledgeable staff and responsiveness any time I've needed something.

Pros

The self-service aspect eliminates calling, quoting, back and forth emails.. just saves a ton of time when you know what you're trying to get done and have a limited timeline.

Cons

If alternative calling plans for lower entry costs were offered I'd definitely be using this in more locations.

Pros

It was easy to set up and after a couple of years of using it, I have never had a problem with it not working.

Cons

Can't think of anything. It was easy to use and there were no problems with it, even a couple of years later

Great Service

Reviewed 4 years ago

They do what we pay for and have not even had to use their backup servers as the primary for has been rock solid.

Pros

SIP.US support team went above and beyond pre and post deployment to allow us to get our phone system up.

Cons

There was an increase in the price of the service a few years back but we really cant complain about going from $.01 to $.012 per min.

Great SIP Trunk Provider

Reviewed a year ago

It's been a great experience overall with nothing really to care about. The service has been rock solid. Even during the DDOS attack that occurred earlier in 2022.

Pros

The ease of setup was fantastic and the documentation that they make for different PBX system makes setup a breeze.

Cons

The customer portal feels a little disorganized to me. I've had to poke around the menus for a couple of minutes trying to find something. Once I submitted a support request to find an option in the website.

SIP.US Review

Reviewed 4 years ago

I'm working on my call center project from home and everything is going fine except the call rejection because of Capacity limit ended....

Pros

The call quality and unlimited US (48) and Canada were the main things which pulled me towards SIP.US. Calls quality is the best, there's no interruption, distortion, breakout or noise in the background.

Cons

No, for my requirements everything is fine except when I see the message "Capacity limit reached.......". I think it should be enough everything on each channel and there should not be any limit for busy signals.

A solution with great potential if your vendor knows what he is doing.

Reviewed 4 years ago

We were affected by the fires in Malibu, CA and tried to implement this as a backup option to our copper PRI line that burned up along Pacific Coast Highway. The issue that prevented us from using this as a solution was the vendor not configuring our device correctly so my review does not reflect the software itself or the potential it had to solve our problem. My lack of a great rating focuses on the difficulty it took to get tech support to work with us when we needed it and the lack of self-service options available online.

Pros

The ordering and setup process was easy. It was fast and easy to work with the Billing group to resolve cancellation and refund. Obviously not software related, but you'll notice how they want you to focus on only software related questions.

Cons

Tech Support was not easily available and in a couple cases took way too long to respond, costing us money with vendors sitting around waiting to connect our system to SIP. Also, equally as irritating, you can only pay by credit card and after your purchasing group has made the initial payment you can't change the option via your online account and everything seems to have to go through their customer service group.

When setting up our system the Technical people at SIP.US worked with our Austrian Cisco Technician and we got both our North American Plants up and running ahead of schedule

SIP.US Experience

Reviewed 4 years ago

As stated previously the whole process has been exceptional. The support team is phenomenal, they seem to have all the bases covered and are willing to go the extra mile in order to make the customers transition as easy as possible.

Pros

I really found that the experience as a whole was very easy. From the initial setup of a test trunk and DID to the porting of hundreds of DID's from our previous carrier.

Cons

If I had to find something I don't like, I would say that the user interface could use a little modernizing.

Recent convert to VoIP

Reviewed a year ago

If you're not technical, and I am not, then it's a steep learning curve. I didn't feel like the tech support was as good as it could be.

Pros

The potential savings and the sales reps weren't pushy. I initially was going with another provider, but their sales team incessantly called me to sign up when the hardware wasn't ready.

Cons

The lack of features and documentation were low points.
