E911 only sending extension and not full number

Hey guys,

I’ve inherited some asterisk systems and have an issue within an office that I can’t figure out. When dialing 911 the call hangs up right after hitting send. I did a pcap and found it’s sending a 4 digit extension instead of the full number. No other office does this.

Any ideas on how to force it to send the full 10 digit number?


Capture the output of your Asterisk Console on a Good call and on a Bad call, Compare them and see what’s different.

Asterisk will forward the incoming caller ID by default. If you want to send something different, you need to set CALLERID(num), possibly by prefixing its incoming value.
