Kaiser TyTnII P4550 phone problem - Call comes in, went straight to speakerphone

[Guest chiewkit]

Hi All,

I recently got myself a Kaiser and one thing has been bugging me A LOT!

This happens regardless of incoming or outgoing calls.

Example: Call came in > I answered as usual by pressing the GREEN answer button > after 3-4 seconds, phone auto switch to speakerphone and I have to manually switch off the speakerphone.

I've tried to soft reset the Kaiser tons of times but still the same crap... I've compared settings with another unit of Kaiser which doesn't have problem... and its still the same problem...

This is getting more and more annoying by day... anyone can help me with this??
