How to 3 Way Conference Call on the Grandstream GXP2170

March 31, 2017 by Steve Lopian

When it comes to phone calls at work, there is no limit to the types of calls we make and receive. Whether you are in sales and marking countless outcalls or in customer service where you are taking countless inbound calls, there is always the element of surprise.

Unless you have a scheduled call or if you are returning a voicemail, you can’t really be sure how your conversation is going to go. Some calls could be a matter of seconds, and others may take hours! This is why it is extremely important to know how your phone works!

Things like putting your call on hold or on speakerphone can be common knowledge, but there are other things that can arise during a conversation that might put some people in a sticky situation.

While there are several different “advanced” things you can do on a phone call, like warm-transfer or transfer someone to a voicemail, for this blog, we are going to focus on turning your one-on-one phone call into a 3-way conference call.

How to 3 Way Conference Call on the Grandstream GXP2170

gxp2170Let’s use the Grandstream GXP2170 as an example on how to bring a third part into your conversation! To begin, let’s assume that you are already on a phone call. Let’s say that you have been troubleshooting an issue for several minutes and need to bring a technician on the line to solve your customers’ problem.

Simple press the conference button on your GXP2170 when it is time to bring in the third party. The button you will be looking for is this: softkey

Once you have pressed the conference button it will bring up the conference dialing screen. From there, dial the third party number and press send! As soon as you have the third party on the line you can then press the Conf/Call softkey to initiate the 3-way conference!

Now you and your technician are able to work together and make one happy customer! When the call is wrapping up,  you can then hit Cancel softkey to drop the third party and resume your 2-way call!

How often do you need to bring in a third party on the line? Is it as easy as it is on the Grandstream GXP2170? Let us know!

    Help Please!!

    How would I conference an inbound call please? Here’s an example: I answer a call that’s intended for my boss. I see my boss is already on a call but wants the new caller brought onto his existing call.

  • How do I exit a conference call but leave both people left in call still able to talk? The scenario would be an inbound call comes in, I answer it, then do a confernce call to transfer to a 3rd party.
