Continuing our series, we answer FAQs regarding business communication systems including VoIP, Cellular & Cloud-based vs On-Site PBX solutions.

SIP Trunks are an extremely effective way of reducing your business communication costs as well as improving efficiency. A SIP Trunk provides your company with a dial tone. They are extremely popular because they consolidate an organization’s connections and are easier and less expensive to operate and maintain.

A traditional premise-based telephone systems will connect to the service provider using a Primary Rate Interface (PRI) circuit and their connections are physical, meaning each circuit requires costly hardware. A SIP Trunk’s connections are virtual and the number of Trunks available is down to bandwidth and not the physical termination or hardware. This enables organizations to save money on maintenance and hardware expenses, paying only for what they need. A traditional PRI circuit provides 23 voice channels and so when an organization decides to scale up they would be required to do so in increments of 23. A SIP trunk can offer automatic or on-demand burst capabilities of any number of paths.

Another significant advantage of deploying a SIP Trunk is in its ability to provide backup and redundancy capabilities. If necessary, re-routing capabilities can quickly and easily enable the distribution of voice services to alternative sites.

Even if you have an investment in a traditional premise-based telephone system a SIP Trunk can still provide significant savings by streamlining costs and resources.

Long distance calls cost less for those using a SIP Trunk and once you’re connected to a SIP Trunk then you have the ability to benefit from a number of rich communication methods like video conferencing and Instant Messaging. In essence a SIP Trunk can enable your company to save money and grow as your company grows!
