Voice conference calls via dial-in and web.

Conference from Melrose Labs allows your team to conduct meetings using voice conference calls and conference rooms dedicated to your organisation. Meeting participants join by dialling-in from their landlines and mobiles. Alternatively, they can join a conference call for free via the web from their desktops, laptops, mobiles and tablets. Calls have high-quality wideband audio and can handle meetings with up to 100 participants.

The Melrose Labs Conference audio conferencing service is possibly the quickest and easiest to get and use. To get service only requires that you provide your organisation name and email address (we completely respect your privacy). We will email you with your conference room details once it has been set-up — usually within one minute of you signing-up. Once you have your details you will either call our Edinburgh conference call number or the 0845 dial-in number to access your conference.

Set-up a Conference Call

To set-up a conference call, firstly sign-up for your Conference calling account. We will immediately set-up your account and email its details.

We'll send the dial-in telephone number (dedicated to your account if on ProGeo plan) and Conference Web Link to join via the web. On Lite and Essential plans we'll also provide your meeting room number. When you schedule your conference calls, share these details with the people you want to take part.

The Conference Web Link allows people to join your meeting for free via the web from their laptop, mobile, tablet or desktop. The Conference telephone number will enable people to dial-in using their phones.

Free Conference Call Service

If you wish to have completely free conference calls, then sign-up for the Conference service and use the Conference Web Link for hosting your online meetings.

With the Conference Web Link all of your conference calls can take place over the web as online meetings, without the need to dial your conference telephone number and incur telephone call charges.

Participants can also join a conference call for free at https://melroselabs.com/goconference/.

Even when you have participants in your conference call using the Conference Web Link, you can still have participants join the same conference using the dial-in telephone number.

Team Communication. Team Collaboration. Team Success.

If you need your team to be able to communicate when they can't be together, then you need Conference.

Sign-Up for Melrose Labs Conference

When you sign-up for a Conference account, we will normally email you every 90-days to verify that you still wish to use your conference room. Simply click on the confirm link or button in the email and the conference room will remain available to you.


   Conference Service Guide


The account details email that you receive when you sign-up for Conference contains all account information that is usually required for you to start using your new Conference account. Simply distribute your Conference telephone number and/or Conference Web Link to participants along with the date and time of the conference call. To join your conference all your participants have to do is dial the number or use the Conference Web Link.

Join a Conference Call

On ProGeo plans, participants dial the telephone number for your conference room to join the conference call and are immediately put into the call. The telephone number is effectively the room number. No conference IDs or PINs are required, except only if a PIN has optionally been set-up.

On Lite and Essential plans, participants dial the service dial-in number and then type the conference room number via their phone's keypad. No PIN is required, except if a PIN has optionally been set-up.

An audio indication will be heard whenever someone joins or leaves the call.

The Conference Web Link can be used to join a conference call or online meeting for free via the web from a participant's laptop or desktop. To join via the web, the participant either clicks on your Conference Web Link or enters your Conference telephone number at https://melroselabs.com/goconference/.


PINs can be added to conference rooms when you sign-up for a conference room.

If your conference room doesn't currently have a PIN, then a PIN can be added to your conference to limit who has access to your conference. Let us know if you want a PIN added to your conference room.

Conference Rooms

You can have as many Conference rooms, each with their own telephone number, under your account as you require. Simply go to the Conference page to add a new room using the Conference service sign-up form.


Each conference room has an upper limit of 100 participants (or 5 participants on the Lite plan). If you require rooms with greater capacity, then please contact Support to discuss.

Dial-In Numbers

The Conference service comes with an 0845 non-geographic telephone number for each conference room, however alternative dial-in numbers can be used. Please note that we do not currently offer 0800 freephone dial-in numbers. Contact Support if any of the following options are of interest to you:

Lite and Essential plans use shared dial-in numbers and conference room numbers that are entered by participants when they dial-in.

  • Geographic Conference Number (aka ProGeo plan): In the UK, we can offer geographic numbers (e.g. 0131 – Edinburgh, 0191 – Newcastle and others) and may be able to offer a local number in your own area. Geographic numbers – instead of using 0845 – are charged to the Conference account holder at £7.50 per month when charged quarterly, and £6 per month when charged annually. We offer a 7-day trial of this service.

  • BYO Numbering+Trunk: You can also bring your own (BYO) inbound SIP trunk and associated telephone numbers for use with the service.

Call Quality

Conference calls take place using wideband audio. If required, we can change audio quality to narrowband (lower quality) or ultra-wideband (higher quality).

Call Recording

Call recording is not currently available.

Calls Costs

Calls to 0845 numbers may be free from BT landlines depending on which calling plan you have and the time you make the call. More information at bt.com.

We do not charge for 0845 dial-in telephone numbers and participants may be charged by their mobile/landline provider when they call these numbers. The service charge for the 0845 dial-in telephone numbers used for participants to join conference calls is 5p/min. The participant’s landline or mobile provider (e.g. BT) may additionally charge an access charge. Some landline and mobile providers do not charge for calls to 0845 numbers. Melrose Labs does not charge participants or the Conference account holder for usage of the service. Participants should confirm actual call charges for their call plan with their own provider.

Calls to geographic dial-in numbers (e.g. 0131, 0161, 0191, etc) are charged at normal local/national call rates by mobile and landline providers.

Participants should confirm actual call charges for their call plan with their own provider.
