FAQ

SIP trunking (Session Initiation Protocol) is the modern way businesses make and manage phone calls over the internet instead of traditional phone lines. It connects your company’s phone system (PBX) to the public telephone network, offering crystal-clear call quality, greater flexibility, and much lower costs.

SIP trunking uses your internet connection to carry voice calls, replacing traditional copper phone lines. Your existing PBX connects to the cloud through a SIP provider like ConnectSIP, allowing you to make, receive, and manage calls over the internet.

Businesses that switch to SIP trunking typically enjoy:

  • Up to 60% cost savings

  • Higher call quality and reliability

  • Scalability without installing new lines

  • Better disaster recovery options

  • Easier remote and hybrid work setups

Yes, you can! ConnectSIP offers seamless number porting so your customers can continue reaching you without any changes.
