Each long-term visitor office has at least one telephone. ICERM phones are available to these visitors for local calls. For all other domestic and international calls, visitors will need to use a personal cell phone, a calling card, place a collect call, charge the call to another number, or use SKYPE.

Dial "8" to obtain an outside line from ICERM phones. For domestic calling, dial 8 + 1 + area code + number. Include the area code when placing a call outside of Rhode Island. The website can be used for directory assistance.

Internal dialing instructions: internal calls within ICERM and Brown University require only the last five digits of the phone number. For example, for ICERM’s main number just dial 3-5030 instead of 401-863-5030.

The fax machine is for ICERM business use only. Please ask ICERM staff for assistance with faxing.
