Global Access Numbers

For international users and participants, Global Access Numbers have been established as a cost-effective method to conduct global conference calls both within your country and outside it.

Below is a list of all Global Access Numbers available to you. Use these numbers only with your Reservation-less Audio with Meeting Management account. If you need Global Access Numbers for an Event Call, please request them when you make your reservation.

Initiating a Reservation-less Audio with Meeting Management Conference using Global Access Numbers

1. On the list below, locate the country you are calling from.
   1. Use Local dial-in Numbers to join conference calls. This is almost always the most cost-effective number to use.
   2. If no Local dial-in is available, it may be less expensive to use a neighboring country's International dial-in. Please check with your local telecom company to evaluate if using a neighboring country's International dial-in is cost-effective.
   3. If you are traveling or out of the office, please use the associated Local toll-free number.
   4. If you are calling from a country not on this list, you will need to dial the international prefix for the country you're calling from, followed by 1-617-786-4658.
2. The chairperson should invite the participants to the conference in advance and tell them:
   1. Date, time, and time zone
   2. The local dial-in numbers for each participant's country (found below)
   3. Participant passcode
3. At the time of the call, the chairperson and participants join the conference by dialing the relevant number identified in step 1. Callers located in North America (Canada, Caribbean islands, and USA) should use 1-888-834-2663 or 1-617-786-4658.
4. When prompted for a passcode, callers should enter their chairperson or participant passcode, depending on their role, followed by #.

Please note: Due to circumstances beyond our control, foreign phone companies may change their numbers without notice. Please review this list often. It is recommended that before the conference, you test the access number from the phone you plan to use during the conference. If you experience a problem, contact the AT&T Voice Conferencing^SM Services Help Desk at 1-800-743-7553 or +1-617-786-4181.

Click to close AT&T Voice Conferencing Services offers these cost-saving solutions for international participants to connect to our US-based conferencing services: International Toll-Free Numbers (ITFN) ITFNs are toll-free numbers that participants can use to dial-in to international conferences. ITFNs are the equivalent of a 1-800 call in the US, so participants dialing in to an international conference using these numbers will not be charged. Direct Dial-in Numbers (DDI) DDIs are local numbers that participants can use to dial-in to international conferences. Participants are using local in-country numbers, so they are charged only for local in-country calls by their phone companies.
