What are SIP Trunks?

 

Many businesses are making the switch to SIP (Session Initiation Protocol) trunks. But what are they?

Simply put, they are telephone lines on your broadband, making calls over your IP connection rather than over traditional physical phone lines (ISDN).

SIP trunks offer a more flexible and lower cost alternative to ISDN for inbound and outbound voice calls, because you no longer need separate phone lines.

In simple terms, here are the advantages of SIP:

  • Call charges are lower – in fact, most calls are free, as it is simply data travelling over the internet.
  • You can keep your telephone numbers – for example if you’re moving or merging offices.
  • Greater flexibility on cloud services – call centre applications, call queuing and call recording are all straightforward.
  • Quick to install and manage
  • Extremely robust business continuity – for example, have your calls diverted to another site in the event of an emergency.
  • Working flexibility – staff working on site or remotely can log in from anywhere using an Internet connection.
  • Scalability – can easily grow with your business. New phone lines can simply be added, reassigned, or removed according to your ongoing business needs.

With the impending BT ‘ISDN Switch Off‘, traditional ISDN phone lines will soon become a legacy product…
