An Oversimplified Guide To Dial-Out & Dial-In Conference Calling

Posted by swarna rani on December 18th, 2019


This is a traditional conferencing practice where a host shares an email or an SMS invite detailing the bridge number and a unique PIN to every participant, which they use to dial-in to the teleconference. Anyone who has the bridge number and unique passcode can join the conference.


In this setup, the host will initiate the call to multiple people at the same time from a single phone, and the conference call begins as soon as the first participant answers their phone. It’s a more modern approach to the conference call, which circumvents the bridge number and PIN process, and ultimately saves businesses revenue and time.

Though dial-in is mired with security challenges, its familiarity remains the primary selling point. There are a few dial-out conferencing apps that offer secure and efficient con-calls, without making the process complex – much like our conference calling app grptalk

grptalk offers audio conferencing services with the flexibility to choose how you conference with both inbound and outbound calls. In dial-out calls, the participants just need to answer an incoming call to join the conference. If you choose the traditional dial-in method, grptalk sends SMS invites, along with bridge numbers, to all participants. They simply have to dial-in the PIN at the scheduled time.
