Advanced Call Manager for Symbian

From WebGate (part of Melon, Inc.):

Advanced Call Manager (ACM) is the app that handles your phone calls just like you would, plus a helpful technology boost. You get more call-handling options (busy tone, busy tone and SMS auto-reply, mute the ringer, divert calls, play a voice greeting) and can personalize your response to different callers. With ACM you can set lists of contacts, choose how to filter their calls, save your call-handling options into Profiles and let ACM run automatically without extra supervision.

It provides you a more efficient call-handling option that you can assign to different contacts. ACM gives you five more ways to subtly escape calls without having to hang up like Busy tone - send a busy tone to callers. Avoid acting rude by hanging up. Busy tone and SMS - add a personal touch to sending a busy tone: inform your callers with pre-assigned SMS replies. Mute the ringer - let the calls through with a muted ringer. More discrete, and keeps you undisturbed. Divert calls - forward incoming calls when you are unavailable. Play a personal greeting (Nokia devices only) - set your own answering machine and record the callers message straight onto your phone, avoiding having to call your operator to check voice messages.

Handle groups of contacts by creating lists with options like Work with blacklists and whitelists - block or allow calls from people included in a list, Import contacts from your phonebook - simplified list creation, Individual settings allowed - personalize how ACM handles an individual caller included in a list (for example, send a specific SMS auto-reply to your mother while the default blocking action for list "Family" is to send busy tone). Create and save different call-management profilesOnce , schedule changes of the active profile according to your lifestyle through Scheduler, and unlimited SMS templates library.
