SIP Trunking

SIP Trunking technology is just one of the many telecommunications services that CMC Synergy make available to clients. With a wide range of services, we’re able to offer the most appropriate solution to each customer’s unique business circumstances.

SIP Trunking is a Voice-over-IP solution where voice telephone calls are converted to data & transmitetd over data lines in much the same way as broadband internet data.

Why use SIP?

  • Reduced costs. Call charges will usually reduce considerably as will line rental charges. Give us a call on 0151 545 0808 for a no obligation chat about your telecoms costs.
  • It’s scalable. Great for expanding businesses that need that all-important flexibility whilst keeping all contact details constant for best customer experience. It’s portable too so can move with a business as it grows, expands, relocates & evolves.
  • You can migrate existing numbers onto the SIP platform or take advantage of different number types to help market your business.
  • Practice excellent disaster recovery – in the event of office disruption through fire, flood, storm or theft, numbers can be quickly re-routed to alternative locations or mobiles to help you ensure business continuity.
  • It’s reliable – exploit the designed-in redundancy of IP based data networks to route around network faults.
