Mosio has Voice Forwarding and we now offer Click to Call. You can choose to forward phone calls to your texting number to another phone number (office phone, for example). The cost is 1 Message/Segment Credit per minute.
To set up Voice Forwarding, visit Tools > Project Settings, then scroll down to Call Forwarding and add a number.
Click to Call (Basic and Plus Plans)
To add Click to Call Services (Basic and Plus Plans only), email firstname.lastname@example.org and Development will turn it on for you. Click to Call costs 3 Credits per minute, so we advise clients to use it sparingly.
