We are interested in setting up an IP Telephony to cut down communication cost especially for overseas calls which translate to SGD10,000 every month.
Number of users : 110
With above requirement kindly assist me on the following:
1. to recommend voice router model, additional switches if needed, IP Telephones models (not the high end type), licenses required to setup IP Telephony.
2. part numbers of the item 1 recommendations;
3. to help check if Cisco Call Manager Express (CCME) has a built in feature or additional license/module required to enable it to automate voice message if the extension number of a particular user has entry on his/her MS Outlook calendar let say out for a meeting or on leave when the call was made that triggers for CCME to launch voice message stating her entry from her Outlook calendar and that such extension user is not available to pick up call.
thanks & looking forward to your prompt response to my inquiry.
