To do that, the old analog voice data is digitally encoded with digital codec. When it comes to switching the signal over, the digital circuit network is initiated and then switched over to the analog. Business VoIP services come with advanced messaging features, auto attendant, web collaboration, and phone access control. Many VoIP providers even have enhanced call center functionality for virtual assistant companies to ensure optimal services for their clients.
A good VoIP phone system will include SIP trunks or gateway servers.
SIP trunks are assigned by the Internet Service Providers (ISP) to forward calls to the right service provider or gateway. In simple terms, these dedicated servers allow you to make phone calls from your computer, laptop, smart phone, or internet enabled mobile device. This is a great way to manage your business contacts and allows you to configure your own VoIP gateway. There are three types of SIP trunks – internal, external, and dedicated. Let’s take a look at each one.
Internal SIP trunks provide internet access functionality and internal traffic within a single VoIP network. These are typically used for internal functions such as message routing, calendaring, and conferencing. External SIP trunks allow organizations to use public switched telephone networks (PSTN) and other external IP networks. External IP networks include Internet telephony, high-speed data networks, and voice over internet access (VoIP).
The benefits of using internal SIP trunking includes cost savings, competitive edge, and ease of implementation. However, when choosing an internal SIP trunking solution, you have to be very choosy as not all companies that offer this service provide the same quality services. For instance, AT&T is a well-known provider of IP phone lines but it does not offer any VoIP phone lines. On the other hand, Cloud Systems can provide both internal and external IP phone lines and they are rapidly gaining popularity due to their extensive range of features and advanced technologies. They are also compatible with leading SIP trunking providers and offer competitive rates.
Another option for SIP trunks is resellers. Resellers offer hosted VoIP services where they manage the entire infrastructure. You simply need to rent their managed VoIP phone lines and access their extensive range of features. On reseller’s part, they charge you for every phone number you forward and they do not own the hardware. They are just like a virtual branch office whereby they handle all your calls from your side and you don’t need to install any extra hardware.
SIP trunks are used in conjunction with hosted PBX phone systems.
A hosted PBX provides all the features of an independent SIP trunking service provider. It makes handling and managing calls much easier and you can concentrate on developing your business. A hosted PBX usually comes with a unique IP phone number assigned to it also comes with auto attendant, call waiting, call forwarding, conferencing calling, music on hold and more. Many companies offer these hosted PBX services but many others do not.
Thirdly, third-party-hosted softwares and devices. Softwares for SIP trunks may be provided by different SIP trunking providers such as Sun Microsystems, Microsoft, IaaS providers, etc. The best part about these softwares is that they can be easily incorporated into your on-premises phone system while maintaining backward compatibility. With the help of these softwares you can easily switch from your on-premise telephone system to a cloud phone system without incurring any additional cost. Moreover, these softwares help you achieve greater flexibility, scalability, and deployment since your existing systems and phone systems would work well with the new cloud phone system you are planning to procure.
- There are many benefits to switching over to a SIP Trunking Provider for your business phone system.
- However, you need to be sure that your business will actually benefit from the switchover since there are some areas that cannot be covered by a standard SIP trunk.
- A VoIP phone system that uses SIP trunking is designed to serve clients at various locations. It allows you to use the same service provider no matter where you are currently located.
- This feature is ideal for small businesses that cannot afford to maintain a separate on-premise system.
