Phone number storage

Phone numbers stored in the directory (Domino, LDAP, or Active Directory) and entered by the user must be in E.164 format. For example:

+13035551212

Phone numbers entered as Preferred Numbers in Sametime Connect and phone numbers entered into the Type a name or phone number Sametime Connect field do not require the leading plus sign. The Conference Service prepends the plus sign to any dialed number before sending the number to the AE Services Server for conversion by the dial plan. Under most circumstances, the E.164 formatted number is the user’s PSTN (public-switched telephone network) number. For customers operating in a non-DID (direct inward dialing) area, an arbitrary prefix may be used to identify non-DID phone numbers and make the extension unique to that site. A dial plan must then be administered to strip the arbitrary prefix and return a valid extension administered on the Communication Manager. The administrator must ensure the LDAP attribute telephonenumber is unique to each user and conforms to E.164 formatting rules. The Conference Service requires two unique telephone numbers with which to execute a click-to-call, which may not be feasible in some non-DID environments.
