It's normal for phones of this type to develop dodgy switch contacts after a few years. A shot of Servisol will fix things unless the switches have actually failed (they are usually cheap, poor quality components).

Speakerphones usually do have a electret mic somewhere which is activated when the speakerphone mode is activated and you replace the handset. You should be able to dial out or answer incoming calls with the handset down if you press the speakerphone button, though the exact operational details vary.
