Solutions to the “Cannot connect. Call in progress.” error on the Blackberry:
1. Soft reboot (alt + right shift + del)
2. Hard reboot (unseat and reseat battery)
Today was the first time I’ve had this problem. I’ve had my new Blackberry Tour with Verizon for about two months now, and today I was on a bike ride when I received a call. I didn’t take the call, and the phone was in standby mode, but it’s easily possible that buttons were getting pressed while I was riding. When I got back home someone tried to call me and it went straight to voicemail. When I started trying to navigate the phone, I would get a “beep” every time I hit the red button to go back to the home screen, and instead of going to the home screen it would go to the past calls screen.
I couldn’t figure out what was going on until I tried to dial my own voicemail and got an error message saying “Cannot connect. Call in progress.” Ok, great, so my phone thinks there is a call in progress. I turned the phone off using the red button, then turned it back on, but the problem was still there. I hadn’t figured out how to do a soft reboot, nor a hard reboot, so I didn’t know how to try those options. So I did a little searching around, and found the answers above. I tried the soft reboot, and that did the trick for me. I still don’t know what caused the problem in the first place, but at least I know how to fix it.
