Why change to SIP trunks?
The use of the Cloud as a deployment model for business applications has become ubiquitous. Today, according to the Cloud Industry Forum, around 80% of UK firms are using at least one cloud based application and this represents a great opportunity to migrate away from legacy voice and data systems to IP based solutions.
Let’s examine some of the many reasons why changing to SIP Trunks would be beneficial to a business:
Starting with a look at costs. When compared to ISDN, where lines are provided in fixed blocks of up to 30, with SIP trunks are provided dynamically. This means that instead of having lines idle that you still have to pay for, with SIP you just pay for what you use and with SI trunks deployed in a network there are no call charges either.
SIP trunks can also be used simultaneously for both voice and data communications enabling many firms to consolidate two or more existing networks down to a single connection.
This versatility and flexibility extends further as by having on-demand scalability firms can immediately respond to peaks in demand and confidently plan for any initiatives that would result in increased call demand.
For organisations that are expanding geographically, SIP enables fast growth. By using networking to combine voice and data, SIP Trunks can connect distant business locations to expand a company’s geographic footprint rapidly.
When it comes to reliability SIP trunks have a huge advantage over ISDN. Rather than being at the mercy of local events such as power or circuit outages, SIP trunking can automatically be rerouted (fail-over) to other offices, mobile phones, or virtually anywhere based on user defined business rules.
Because SIP can be delivered across high bandwidth connections such as Fibre, and Ethernet in the first mile (EFM) higher levels of vocal quality can be delivered from end to end.
This means that customers can make and receive HD quality voice calls, assuming of course their handsets are compatible.
Additionally, with services not necessarily relying on a single connection, SIP services could utilise a primary service with automatic failover to a second path, which is not available on ISDN.
No matter what the cost the most significant factor to consider is return on investment (ROI).
With SIP there is little significant capital expenditure. The business applications are significant, especially when considered in the context of exploiting the benefits of Unified Communications to achieve customer centric strategies and knowing that should fate deal you a bad hand there is an automatic failover of SIP communications to alternative sites for business continuity is highly advantageous.
