Abstract
The present invention regards method and apparatus relating to wireless office system. The present invention addresses the problem of enabling it to be determined in the wireless office system (5) when voice mail messages for users of mobile stations having subscriptions in the wireless office system (5) are received at the voice mail system (15), the voice mail system (15) being associated with but not included in the wireless office system (5). The duration(s) of greeting message(s) associated with the voice mail system (15) and the or each mobile station having an associated voice mailbox (16b1-16bM) in the voice mail system (15) is/are measured. The connection times to the voice mail system (15) are measured when calls for the mobile stations are forwarded to the voice mail system (15) from the wireless office system (5). By comparing the duration(s) of the greeting message(s) with the measured connection times, it is determined whether voice mail messages have been received.
