We mostly have Sangoma phones. S500, S505, S705.
I would like to be able to dial 911 without a delay.
I am not super familiar with dial patterns, I always just left the defaults. Through some testing, this seems to work
Dial Entry Timeout 5
Dial Now Timeout = 0
We have the emergency routes and emergency callerID all setup. (been there for years) Never had 911 go the wrong location. We had one issue where a person dialed 911, thought the call did not go through because of the dial delay.
During an emergency people get excited, one second can seem lot a really long time. After this instance several managers questioned the emergency reliability of the system. I was able to show exactly what happened, but would really like for it to not happen again.
