Frequently asked questions about SIP trunking

Rebecca Jenkins

• What is SIP trunking and how does it work?
  • SIP trunking is a way for businesses to move their communications from physical hardware to internet-based services. It works by connecting PBXs to a SIP provider, which uses SIP to move communications onto virtual ‘trunks’ on the internet – making it a secure, efficient, and scalable way to manage enterprise-level communications.

• What’s the difference between SIP trunking and VoIP?
  • VoIP (Voice over Internet Protocol) is a method of delivering voice calls via the internet. SIP trunking is a way of implementing VoIP, using it to connect phone systems to the public telephone network.

• What are the benefits of SIP trunking?
  • SIP trunking offers cost savings, flexibility, scalability, and easy access to advanced call features.

• What are the benefits of SIP trunking compared to traditional phone lines?
  • Costs: SIP trunking eliminates the need for phone line rentals and the associated maintenance costs that come with traditional systems.
  • Flexibility: SIP trunking supports a mobile or dispersed workforce with communications able to route to different locations rather than being tied to a physical office.
  • Scalability: While traditional telephony requires physical upgrades to scale with demand, SIP trunking can enable this from within online portals.
  • Enhanced call features: Accessing advanced call features is easy with a SIP trunking system, whereas these upgrades may rely on physical hardware changes in a traditional system.

• Can SIP trunking work with my existing phone system?
  • Absolutely. Through our HALO Platform, Sipcom can facilitate integration and interop with existing business systems, PBX/UC platforms and supplier relationships. This ensures that feature requirements, which may not be available natively, can be met and allows customers the option of a phased migration path with the co-existence of existing technologies during transition. The HALO Platform offers a Bring-Your-Own-Carrier (BYOC) service which allows organizations to consume SIP-based PSTN services from multiple suppliers. BYOC offers businesses ultimate flexibility by allowing them to bring their existing carrier into our environment, meaning no more early termination charges, no need for porting, and no need to purchase new numbers.
