IP Office Mobile Call Back
To avoid any call charges when using a mobile phone the IP Office Mobile Call Back feature has been implemented: When calling a particular number at the IP Office, IP Office will reject the call and will call back the mobile number if this number has been identified as an eligible one. After accepting this call the mobile user gets a dial tone and can establish another call. Depending on the service provider’s tariff, there are no call charges (except possible roaming charges) on the mobile invoice. IP Office Mobile Call Back is very useful for employees using their personal mobile phone for business only from time to time: their personal mobile phone number stays confidential and they do not to claim mobile charges back from the business.
