Voice over IP

Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analogue) phone line.  

With a VoIP network, you are limited only by bandwidth, so thousands of connections can conceivably be made.

VoIP comes with a wide selection of extra features like call forwarding, call waiting, voicemail, caller ID, three-way calling and more.

Disaster Recovery

One of the benefits o SIP trunking is how well suited it is to disaster recovery. To keep your telephony service active, a secondary internet SIP service provider is strongly advised. This back-up strategy means calls will be redirected to your favourite provider should your primary SIP service fail. 

Many businesses are used to landline phones that function through disasters, failures and emergencies. The new technology, SIP, can drop-out due to software issues, loss of internet or a power cut.

Business continuity is key to us here at Evotec and with this in mind we recommend a Disaster Recovery plan to all of our clients, the inclusion of a 4G back-up to your DR plan will help in the situations where your primary service provider fails.

  • SIP, by its design, unfortunately, has more points of failure than ISDN and PSTN
  • Two types of situations may occur
    • Disaster strikes the business
    • Disaster strikes the VoIP vendor
  • A secondary SIP service provider is highly recommended
  • SIP Trunking is well suited to disaster recovery
  • This back up means your calls will be rerouted to the failover provider should your primary provider fail
