Questions on Grandstream GXW4004 (Discontinued)

From Daniel John at 11/1/2015 7:00 PM

Q: How can I configure E911? My voip provider states a sip address that 911 should route to, but I cant find any way to add this to the dial plan.

A: Hi Daniel,

What phone system are you using the gateway with? Your DID should have an address associated with it to provide 911 with your correct location.
