Great for trunks and hosted Asterisk
It provides an automated IVR service for our clients, and routes inbound calls to our operators.
- We have had a hosted asterisk service with SIP
- US for almost 8 years and we liked that we have been able to add custom code to our service to be able to better meet our needs
- There hasn't been anything that I would describe as a con

Mostly good, some missing features
Overall we are very happy with the SIP.us solution. We have contractors all over the world, so having the ability to call people all over
- Ease of integration with the PBX (we use Asterisk) - Clear user guide and documentation
- - Mostly good for calls made to North American and western-European numbers
- Not so good for international calls, especially to some countries - India, Russia and some Eastern-European countries (Romania, Bulgaria, Armenia come to mind)
- Some providers in these countries seem to detect that our calls are Voip calls and block them
- And we have raised this issue with SIP
- us, but received no feedback
- This means we have to spend more money making phone calls via Skype
- And Skype calls are expensive but always go thru, unlike calls made via Sip
- us trunk lines
- Now, I understand you may say it is not your fault that telcos are blocking calls made thru SIP
- 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
Why they chose it
"We have not exclusively chosen SIP over SKype. Rather, Skype complements the one area where SIP still fails us - making calls that are blocked because some telcos detect them as Voip calls."

UNSATIFIED CUSTOMER
so far terrible service, with little to no feedback. This is definitely not what I was hoping for in a company.
They merge successfully with Zoiper other than that so far i have complete wasted my time waiting for the services i paid for
- I Paid for the services and i even wrote a ticket because their services still have me in demo mode after payment was received
- I tried calling the customer service number, guy male who answered stated he can't assist me with the setup of my account so far, I'm definitely dissatisfied

Fantastic SIP Provider With Excellent Technical Support
We use SIP.US as the phone provider for our office's 40-extension phone system. We currently have toll-free and local numbers (DIDs) with them as well as some fax numbers.
- - Completely self-service website
- - Fantastic technical support that responds within minutes, usually
- - Automated number port-in process
- - Huge inventory of DIDs across the country
- - SMS service is available on most DIDs
- - Website is a little outdated
- - Pricing is just fair, not great
Why they chose it
"Friendliness of support agents and instant account activation."

SIP.US VOIP Service Review
Verified reviewer
- This service was very easy to setup and has been rock solid
- There was a complete guide on how to setup our Grandstream UCM PBX with SIP
- US and SIP
- US also provided a phone number with the service
- They have redundancy options and the quality of the phone calls are just fantastic
- The toll-free cost per minute could be cheaper but really that's a minor issue
- the overall experience has been excellent
Switched From
The price points were much better with VOIP, we finally got CallerID, and we have more control over fail-over and other options.
Why they chose it
"We use both - but our main product is SIP.US - the reason being is that it has been very stable and dependable."

SIP.US for Backup Phones
We use SIP.US to handle our calls and send them to voicemail when our main line is down. They have worked great for that purpose, and thankfully we don't have to rely too heavily on their service.
- SIP
- US works great for our backup phones
- We use it irregularly, which means our main phone system is working, so that's good
- The UX seems to have gotten a face lift recently, so I have been exploring it a bit to see if there are new features
- 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
Why they chose it
"SIP.US offered us the best flexibility, and the option to pay for what we use. Most other options would have a base cost that exceeded what we wanted to pay."

Easy and Expensive
So far so good
- Easy to use, well explained, website is clear, simple and organized
Expensive, I don't have the ability to create sub-account for each of my clients under my name
Why they chose it
"Twilio has so many services and I was confused at the beginning, Sip.us was simple and clear to understand for a beginner"

Your experience may vary
I inherited the phone system from the original individual whom had passed away prior to my being hired. Though the user experience has changed with an overhaul over the main site itself, there are still many things that are a pain to do. The bills are also very vague & fixing charges has been a massive pain. Items will have generic listings and refer to something you wouldn't have even thought of. I've tried since January to get credited for an item I was told was 1 thing but turns out it was something we no longer had and while it was removed, the credit was never applied. Weeks can go by without a response to a query or action is taken without a response back. Part of these issues could very well be that I am not the primary on account, but I am the one that handles it. Improving the communication could possibly do wonders for the business as a whole.
- You can login via root and make changes to system via command line
- This can be a big plus if you're wanting to make custom edits or security changes to the system to meet your companies' needs
- The servers were not kept up to date by provider as I was told they would be, so our software has fallen too far behind the current available branches to update
- This mostly means I have to keep within specific lines of phones and forced to manually deploy each new phone
- This also means that I don't have access to command line tools I would normally have to trouble shoot connection issues the OS is way out of date as well and can't be updated without a massive headache which I haven't found to be worth the effort

SIP.US as SIP Trunk Provider
Using SIP.US, I was able to lower my monthly phone costs by 10s of thousands of dollars per month.
- I had poor results transitioning from POTS/ISDN to SIP with another provider
- SIP
- US made the port much simpler and handled the interaction with an uncooperative telco
- The website management capability is outstanding
- Updating e911 data as people move locations is as simple as entering the info and clicking SAVE
- The support portal is easy to use and very responsive
- Detailed billing is easy to view
- The one are that could be improved is notifications when you exceed trunk capacity
- Rather than a notice that you exceeded it at some time in the past month, I'd like something closer to real-time notification with time/date to allow me to better adjust my trunk requirements
Switched From
They were unable/unwilling to follow through on the initial port. Support was unhelpful, leaving me to attempt to broker between two companies - neither of whom would work with me.
