Great for trunks and hosted Asterisk

It provides an automated IVR service for our clients, and routes inbound calls to our operators.

Pros

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

Cons

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

Pros

- Ease of integration with the PBX (we use Asterisk)
- Clear user guide and documentation

Cons

- 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?

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.

Pros

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.

Cons

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.

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.

Pros

- 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.

Cons

- Website is a little outdated.
- Pricing is just fair, not great.

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.

Pros

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.

Cons

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.
