If you want for example an area code 416, 613, 514, and 604, all to route to your Toronto office phone system; with TDM (PRI and analog lines) this would be very difficult to deliver, with SIP trunking it comes standard.

Scalability is important in communications because it refers to the ability of a communication system to handle increasing levels of demand or volume without sacrificing performance, reliability, or quality. In the context of modern communication technologies, scalability is critical for supporting rapidly growing numbers of users and devices, as well as handling increasingly complex and data-intensive communication tasks.

Without scalability, communication systems may experience performance issues, downtime, or even complete failure when faced with high levels of traffic or usage. This can have significant negative impacts on business operations, customer satisfaction, and revenue. Therefore, designing and implementing scalable communication systems is essential for ensuring reliable and efficient communication both now and in the future.

Disaster recovery is essential in communications because any interruption or failure in communication systems can have serious consequences for businesses, organizations, and individuals. Communication channels are critical for delivering vital information, coordinating actions, and maintaining relationships. In the event of a disaster, whether natural or man-made, communication systems can be compromised, disrupted or even completely destroyed, leaving businesses and organizations unable to communicate effectively with their stakeholders.

Number flexibility with SIP Trunking means that you can keep your existing number, even when moving out of the area, saving you costs on printed company literature and stationery whilst maintaining the perception that you still have a presence in the area you’ve moved from.

Does your business have multiple sites? Do you have a PRI connection into an individual PBX at each site? By using SIP Trunking, you can reduce the number of PRI connections that your business requires and also reduce the maintenance costs on all of your various PBXs. At the remote sites you are left with just the cost of an IP connection and the handsets that you need and you can then pull all the telephony traffic back into your centralized PBX.

Not only that, but SIP Trunking also increases your resilience because you can build an automatic fail over system into your communications strategy for lines and calls, should your main site go down. With SIP Trunking you can instantly centralize and distribute the calls somewhere else, to another site or to home workers for example.
