Have anyone any experience when the conference soft button is suddenly not available? It is not the phone template.
We have a glitch this morning when 2 phones can not conference calls.
It was happening for 3 times and it is resolved after that.
Basically, A call B and then A put B on hold. A call C and then when he tried to conference it the conf soft button is not available.
The phone is Cisco 7975.
