Just wondering if anyone else has had any issue with the switch hooks on the 24 button SBX phones. I have two from one site. They work OK, but every now and then they act like the spring gets tired on the way up. Customer complains about not connecting with callers, can't hear and etc. Found the problem just by pushing the plunger down about four times in a row. At least it's not like the old STS phones with the broken switch hooks. lol
