Utilizing over 30 years in the telecommunications industry
SIP stands for Session Initiation Protocol and is one of the methods used to replace Primary Rate Interfaces (telephone lines). PRI is a T-1 transmission technology that has been widely used to support voice communications for over 40 years. A PRI circuit includes 23 voice channels to support 23 concurrent calls, and one data channel to support call-related functionality like caller ID. Voice calls that are supported through PRI technology are submitted as electrical pulses and routed through traditional telecommunications carriers. Traditional telephony requires a relationship with a telecommunications company and on-site servicing of cabling to add lines or upgrade equipment. SIPs are an excellent way to send and receive video and audio messages using the internet. They work in conjunction with PBXs (link) to create a secure infrastructure, and are particularly useful for companies with over 30 employees and/or multiple locations. For organizations with hosted phone communications, like True IP Solutions UcaaS platform, SIP trunking equipment is hosted and maintained by TIPS to manage the transmission of voice data. SIP is an alternative to PRI in that it completely eliminates the need for traditional phone infrastructure, including circuits.
What are the Benefits of SIP Trunking?
Since SIP trunking eliminates the need to work with a traditional phone company, it’s biggest advantage is that it can be a major money-saver for businesses. No traditional phone lines means no huge monthly phone bills, no long-distance charges, and lower maintenance fees. With SIP, your company will be able to take advantage of virtually limitless calls to wherever you want.
Some additional advantages of SIP trunking include:
- Easy scalability when it comes to adding/removing lines
- Offers failover to mobile phones in case of loss of office data connectivity
- The ability to integrate new/existing UCaaS features (instant messaging, various applications, etc.)
- Enhanced reliability over traditional phone lines
- Compatibility with most newer phone hardware
- Offers simple support for multiple sites and remote workers
- The ability to use the same phone numbers without getting new ones
Head to Head: PRI vs. SIP on 4 Key Business Considerations
For the vast majority of organizations, SIP is much cheaper than PRI. Cost is an important consideration for organizations, even though it’s not the only factor to take into account when you’re investing in a business phone system. Organizations that need to scale their system, add features, and perform long-distance calling are likely to achieve massive cost savings.
PRI is considered more secure, which isn’t strictly correct. Copper cabling can be subject to a number of information security risks, including interference and interception. However, organizations that lack on-site information security expertise to achieve adequate network security and attempt to run consumer-class VoIP over public internet connectivity may be very vulnerable to security risks.
The biggest con to PRI is also among the greatest pros of SIP trunking; flexibility and scalability. With PRI, organizations are required to purchase additional user capacity in 24 lines. With SIP, organizations can add a line for a service month to accommodate a temporary or seasonal employee, and remove the line as soon as it’s no longer needed. SIP can enable organizations to unlock truly usage-paid billing on-demand, while organizations using PRI may need to wait weeks to schedule a technician for very high-cost infrastructure upgrades.
The reliability of copper-based phone cabling can be damaged through a number of risks, including inclement weather, vandalism, or simple degradation of an aging infrastructure. While PRI is considered a very reliable technology and it generally is, organizations will lose access to phone service if a component of their infrastructure is damaged. SIP is reliable, provided organizations partner with a reliable vendor and invest in high speed internet connectivity which is very resistant to weather and other common types of damage. With mobile failover, organizations can continue using dedicated phone lines even if there is a loss of data connectivity on site.
