Good service, great provider, tad pricey though

Overall experience has been good. The major thing I wish they had is a 24/7 phone number that I could pick up the phone and call for tech support. When we do cutovers and new projects it's usually done after hours or on a weekend to avoid cutting into business hours, so having support 24/7 would be hugely important to tech people like me.

Functionality

Pros:

Service is outstanding, don't have to deal much with dropped calls or latency issues. The web interface is intuitive and easy to use, and most importantly the support is pretty good (email/ticket only though, really wish they offered more support over phone)

Cons:

I don't think they have phone support that you can call in normal, if they do please let me know and I'll modify this review. Only other drawback is cost is a tad higher than some others out there. But SIP.US is pretty easy and reliable.

Reasons for choosing SIP.US

Because I've used before and they are easy to manage/work with. And because quality of call service has been good so far. A lot of cheap providers route calls far away (sometimes overseas) and that causes high latency and more dropped calls.

Reasons for switching to SIP.US

Because CBeyond is a horrible company that manipulates and takes advantage of customers by means of tricky contracts and practices that are illegal in a lot of states (like auto-renewing your contract for 12 months at a time if you don't cancel within 21 days and in writing).

Pros:

Customer direct control of call routing.

Cons:

Problems with compatibility and support connecting with some IPPX routing systems, such as Ward Mudy's IncrediblePBX software on a computing platform of the customer's choice for maximum cost efficiency and features/capabilty support.

Reasons for choosing SIP.US

The straight forward customer control interface combined with direct support, by email, by the [SENSITIVE CONTENT HIDDEN]. [SENSITIVE CONTENT HIDDEN] answers were commonly a bit over-my-head, experience level, they were always helpful, helped my solve connection problems (usually rapidly) and offered a winning customer experience.None of the other SIP.US support reps have ever been quite as helpful as [SENSITIVE CONTENT HIDDEN] routinely was.

Reasons for switching to SIP.US

Cost first! Flexibility to control calls second

SIP.us service

SIP.us allowed me to be operational on multiple platforms. Integration is simple, number selection is good, and implementation is fast. I had a client that needed to LNP 100 DID's and get services up quickly...SIP.us team had me up and working within 2 hours. The numbers were ported very quickly with no issues.

Pros:

It's easy to use and it gets the job done. I've been using the service for over 4 years and it's been fantastic. I use it with X-Lite, Cisco CME, Kerio, Cisco phones converted to SIP, GrandStream, etc. The documentation around setup is easy to follow. I'm a consultant and i travel all over and i'm able to connect where ever i go.

Cons:

I've had a few issues with address validation when setting up billing...but i made a phone call and support resolved it over the phone. I haven't had any issues with service.

Excellent & easy to use service.

Have been connected to SIP.US for many years. They've updated the web site to make it even friendlier and self-service is a snap. The only issues I've run into were local to my network & ISP but the support team was able to provide enough clues as to likely cause that I was able to get things up and running.

Pros:

I have a home lab with a couple of Asterisk servers. Provisioning trunks & numbers is a breeze. I do contract work for businesses in London & Auckland and setting up a local DID is super helpful. Since my usage is quite variable I really appreciate the prepaid pay for what you use plans.

Cons:

Haven'r run into any snags. I would appreciate SMS options for significantly less cost (although I haven't looked into this in a while).

SIP.US saved the day and changed how I look at phone service forever.

When I happened across SIP.US in a google search on the weekend when our physical phone system crashed and we had to build a virtual one quickly and get it up and running before Monday, I had never used SIP trunks before. I had not used them because I was unsure of the technology and worried about call quality, the phone company always wanted to bring in a separate circuit to run SIP trunks (more bureaucracy and red tape). SIP.US was fast and easy to get going and JUST WORKS! We enjoy great call quality with SIP.US and have the flexibility to add and remove phone numbers and trunks at will. We can respond to market conditions instantly scaling up or down at will. I wish I would not have waited so long to give this service a try it really does change the way that we think about voice service. I suggest using the free trial and just giving it a shot, once you sign in and see the portal and all that you can do INSTANTLY you will be hooked.

Pros:

SIP.US is very quick and easy to set up and use. I set it up at around 10pm on a weekend when our phone system had died and we had to recreate a virtual one that could not connect to our existing PRI. Without talking to anyone I had a SIP trunk up and taking calls in less than half an hour without having any previous SIP trunk experience. The next day (on a weekend!) I received a call from the executives at SIP.US to make sure I had everything that I needed. The support team proceeded to help us get all of our numbers ported as quickly as possible (you can do this from the web portal but they were just being nice.) Once I understood the ease of use (no calling and waiting for the phone company to wait through their bureaucracy), reliability and clarity of using SIP trunks through SIP.US I could no longer imagine relying on a traditional phone company for phone service. SIP.US is a game changer, we have never looked back. SIP.US is how phone service should be.

Cons:

I have not found anything to dislike. SIP.US does what it says it is going to do and keeps on doing it. Full control of my phone service from a web browser, what's not to like?

Pros:

Sip.us easily integrates with our Asterisk PBX. Their customer portal is simple and straight forward to use. We have been using them for years and their uptime has been excellent.

Cons:

When we had an 800 number, we had to pre-pay blocks of dollars for those calls. It was awkward from an accounting standpoint. We don't have the toll free number anymore so that is no longer an issue.

Reasons for switching to SIP.US

Clarity only supported Asterisk as a side business and it was difficult to work with them. Sip.us had competitive pricing and they offered complete support for Asterisk.

The timely support when I was having issues with my software or my clients software interfacing with sip.us was invaluable. They contacted me directly when there was an administrative (billing issue), which was appreciated. I also like the flexible services and ability to setup trunk accounts.

I'd like to see some advances in encrypting the sip traffic and the ability for me to resell trunk accounts to my customers

Pros:

Fairly simple to implement. Over the past seven years I have used the service it has been very reliable.

Cons:

Billing can be a bit confusing and customer service a bit difficult at times. This situation has improved over the years however. You have a mix of prepaid and billing which can cause confusion and extra steps. DID billing doesnt come out of prepaid funds like most services. It is billed seperatly and cannot be prepaid.
