I'm hoping someone else jumps in here. But I'll start by asking for some clarifications:
Q1: Is there a local, ten-digit number at your daughter's location that connects directly to the local 911 center?
If yes, then the process is documented on here, if you are unsure which thread to follow reply back.
If no, I'll take a leap of faith and guess the way to do this is "digit map" 911 to "**2911", or simply route 911 to SP2 (your call centric service configured on ITSP B). That means when you dial the 911, the obi either remaps it to **2911, or routes 911 to SP2.
Someone else needs to jump in on the "if no" answer.
