The amazing thing about Squaretalk is they were able to take something that must be highly configurable, sophisticated and complex and turn it into super compatible and clear software. In addition, their onboarding and customer success teams went out of their way to integrate the solution with the business tools that we are using (including some that it was not designed for) and made sure that everything, to the smallest resolutions, works perfectly.

FAQ

What is a SIP trunk in VoIP?

A SIP trunk is essentially a virtual phone line that uses the internet (rather than old copper lines) to carry voice calls. It connects your business phone systems (PBX) to the Public Switched Telephone Network (PSTN) over a secure data connection.

In many contexts, the terms used interchangeably. However, generally:

  • IP trunking might refer to any technology carrying voice over an IP network.
  • SIp trunking uses the Session Initiation Protocol (SIP) specifically, which has become the industry standard for VoIP.

HD VoIP SIP trunking can be as reliable as traditional landlines which often deliver clearer sound quality. The key is ensuring you have sufficient bandwidth and a reliable ISP to avoid call drops and latency.

Benefits of HD VoIP SIP trunking include:

  • High-quality audio for more natural-sounding conversations.
  • Cost saving  – lower monthly bills and reduced hardware maintenance.
  • Scalability – add or remove channels quickly as call volume changes.
  • Advanced features like call analytics, failover routing and integration with modern cloud systems.
