Your speaker might be faulty and beyond that your phone is EOL'd (end of life) so you're not going to get any software updates. Check if your phone is diverting to the headphone jack when you're on a call, I had this happen once or twice on my Lumia 920. A soft reboot fixed it, holding the volume down and power button at the same time.

Your only other option is to buy another phone.

Are you using an Invoke on the same network?
