Verify you have the following OutboundCallRoute:
Physical Interfaces -> PHONE Port -> OutboundCallRoute:
{([1-9]x?*(Mpli)):pp},{(<#:>):li},{911:sp2},{**0:aa},{***:aa2},{(<**1:>(Msp1)):sp1},
{(<**2:>(Msp2)):sp2},{(<**8:>(Mli)):li},{(<**9:>(Mpp)):pp},{(Mpli):pli}
If you do, call your local non-emergency police or fire department number and explain that you have a new telephone system and would like to make a test call to 911. Once you have permission, make the call to 911 and immediately tell the dispatcher who answers that there is no emergency. Verify they have the correct information in front of them regarding your name, location, etc.
