conference call commands

“Whose dog is that barking? Can you mute your line? Is everyone here? Who’s actually on this call right now?”

Ring any bells? Regrettably, when it comes to conference calls, these issues simply come with the territory. But what makes these interruptions infinitely more irritating is when no one can offer any solutions! Too regularly have hosts had to completely abandon their call in order to start all over again, wasting everyone’s time.

More often than not, the issues plaguing your conference call can be solved by the host or even the guests themselves by using DTMF (dual-tone multi-frequency) commands.

The simplest DTMF commands should be pre-requisite knowledge for anybody who frequently hosts a conference call. To help bring everyone up to speed, we’ve compiled all the DTMF commands that can be used on a 247meeting conference call.




Start recording (host only) – When the host enters *2 during the conference, the call will begin recording itself.


Playback the recording (host only) – Having selected *2 and started recording your call, use *3 to playback the recording for a re-examination of what’s been said.


Start lecture mode (host only) – When the host enters *5, they will have begun lecture mode, where all lines are muted with the exception of the host. Guests can unmute their line by selecting *6.


Turning mute on/off (all lines) – Mute your line. Whenever you’re not contributing to the call, you should mute your line to avoid any distracting background interference or heavy breathing!


Lock your call (host only) – An extra security measure for the host to put in place. By locking the call with *7, no one else can join the conference call.


Roll call (host only) – Roll Call can function differently depending on how you set up your conference call. If you have ‘Name on Arrival’ switched on, where guests record their names when joining the call, Roll Call will announce how many guests are on the call and repeat everyone’s recorded names when*8 is entered. If ‘Name on Arrival’ is switched off, *8 will just announce how many guests are on the call.


Lower hold music volume (all lines) – When waiting for the conference call to begin, you may hear hold music. If you would rather hear less of this music, guests can enter *97 to lower its volume.


Normalise hold music (all lines) – If you have lowered the volume of the hold music, you can return it to its original volume level by entering *99.


End conference (host only) – The conference host can terminate the call by entering ## at any stage.


Find & mute noisy line (host only) – If there is consistent, unwanted noise on the call, the host can enter #1 and find the source of this constant noise, it also automatically mutes the line once the source discovered.


Mute all guests (they can’t unmute themselves) (host only) – Differing from lecture mode, where your guests can unmute themselves to speak, entering #5 will mute all guests and prevent them from unmuting themselves.
