Traditional voice services have had their heyday. Today, developing technology trends are shaping a new future for business communications. Automation, the Internet, mobility, cloud, and more are triggering shifts in new services that meet changing customer demands. Session Initiation Protocol (SIP) Trunking is emerging as not just an option but a compelling choice for the modern business.
Focusing on the benefits
Even as voice converges with text, image, video, desktop, mobility, and social media technologies, many network administrators still fear the unknown. Their priority is to maximize and protect their investment so it’s understandable that many proceed with caution. However, in order to steer their business forward, network managers should consider what could go right.
For instance, SIP Trunking has many benefits if best practices are observed.
- Savings. In an SIP environment, IT managers start realizing savings when they phase out costly infrastructure. SIP Trunking eliminates Primary Rate Interface (PRI) and Integrated Services Digital Network (ISDN) rentals. Businesses can also save costs by using centralized public switched telephone network (PSTN) access. This can eliminate costs for maintenance, operations, and unused services.
- Scalability. SIP eliminates the problem of having too many channels when they are not needed and too few channels when more are needed. It can be scaled up or down on a per-channel basis to suit specific business needs. It also enables businesses to add trunks as demand dictates.
- Flexibility. As a Unified Communications (UC) package, SIP offers significant flexibility with an array of collaborative options. End-users can enjoy web, voice, video conferencing, instant messaging, chat, voice traffic re-routing, and mobility options.
- Reliable disaster recovery. Security and recovery can be major fears. SIP Trunking features reside in the IP provider’s network in multiple sites, not in the customer’s premises. Should a disaster occur, businesses are assured of timely disaster recovery (DR) and business continuity. This allows calls to be redirected to locations not affected by the disaster, ensuring a recipient for each incoming call.
Hurdling the obstacles
While SIP is a versatile technology, moving to an SIP model has its own challenges. The most common one is interoperability issues. Different vendors interpret SIP specifications differently. This can create complications when integrating legacy systems with the SIP provider network. A good provider should re-evaluate the customer’s existing architecture and suggest modifications that can support the new services.
Bandwidth capability is an important consideration for SIP connection. Bandwidth determines the quality of calls. The wrong amount of Internet bandwidth and such issues as latency, packet loss, and jitter can result in echoes, garbled messages, and call disruptions.
Connecting to the Internet exposes any network to security threats. Brute force and Denial of Service (DoS) attacks are common issues that can cause entire networks to crash. Solid firewalls, session border controllers, and other security devices can help ward off such attacks.
For IT executives, transitioning to SIP Trunking is a critical decision. Decision-makers should consider an SIP deployment that can support present business needs and easily adapt to unforeseen collaboration services well into the future.
