When you change carriers in a PRI to SIP migration, and you are doing SIP trunking, you have to make sure all phone carrier switches are being updated with your new carrier information. Every phone company, for the most part, has their own switch. When a number changes, all these switches have to be updated with the new information. In some cases, a switch or two will get left behind in the process.
For example, you change to a new SIP carrier, and a customer in Wichita tries to call your number and can't get through. Customers usually place the blame on their carrier, because their calls are not getting through. What is frequently happening is not a problem with the carrier you switched to, but the carrier of the caller has yet to update their switch. The Caller ID situation is much the same. When you switch carriers, caller ID can be a detail lost in the transfer and must be managed to ensure it is correctly displaying to your customers.
You must proactively address caller ID and make sure it is being announced properly. You also should actively address switch updates, making sure your customers will be able to reach you when they need you. These first two factors seem scary on the surface, but if your new carrier is worthy of your business, they will help you and make sure your phone service is being delivered successfully.
With Centrex, phone companies could act as a sort of PBX, which was attractive for businesses who needed the functions of a PBX, but could not afford one, or chose not to purchase one of their own. Centrex was a precursor to a PBX in the cloud; it was the original hosted phone service. This brings a new level of affordability to companies who need the PBX functionality , and they don't have to invest in costly equipment or maintenance. It's all done in the cloud with a software-based, Hosted PBX system.
Years ago, switchboard operators would set up and tear down phone calls, making sure someone's phone call was connected to the right line. Then, a system arose which automated that process called, SS7, or Signaling System 7. When you are using SIP, you also need the ability to setup and tear down calls. But there is also an additional functionality an SBC provides; the demarcation point. Like a firewall for your phone, it can permit or deny calls based on predetermined criteria.
