Just an a instance of I was in a call and had to dial a number followed by the hash key, when doing this the call I was on dropped. What is the cause of this and how can it be prevented?
A tone sound from... the party you were calling? Did the disconnect come when you heard this tone, or when you actually dialled a digit? Was this calling another extension on 3CX , or an outside call? Has this happened when calling any other destination?
