When being transferred to an extension the current system just cycles back to a generic question of "how can I help you" if the transfer extension does not pick up. this makes it look like the AI did not understand or respond to the instructions and it frustrates the **** out of the caller. We have had multiple callers just hang up, which we determined both by calling them back and by reading the transcripts. Please give the system the ability to determine if an extension is busy and the ability to convey that information to the caller. This really should have been a base feature in the system before you even went live since telling someone the person they are trying to reach is busy is kinda a critical thing.
