Text Message Notification while on a call

[zachavm]

My wife has been having an issue that unfortuantly I'm not around to look at (out of state on business). Anyway, I thought I'd ask the smart forum peeps about this.

During a call, she has no notification that she's gotten a text. She needs this as her job is done almost entirely through calls and text and she needs to respond immediatly. Anyone know if there is a setting to change this?
