So we have call forwarding setup during business hours
The sequence is
1. Landline Number (Cable service)
2. Business A cellphone #
3. Business B cellphone #
4. Business C cellphone #
Our problem is when the landline phone (1.) is in use, I'm assuming the next ring will go to Business A cell number, but it doesn't, we end up missing the call entirely. As a healthcare business, all calls are important to us. Please advise.
