Yes, you can set up the system so that, when a call comes in, callers are put on hold until someone can take their call. Our system will try to call each of your phone numbers in order, indefinitely, until someone picks up.
To set this up, go to Extensions and click Edit on the extension, then click Options:
Within the "This extension should call each of my phone numbers" drop down, you can then choose for the call to ring your numbers indefinitely, until someone picks up.
Please note: When "indefinitely, until someone picks up" is selected, a message will be added that says "You may press star at any time to go to voicemail". We are unable to remove this message if this option is selected.
