Outbound Caller ID Rule

[Heath]

Currently in my SIP truck, I have in the caller ID tab Our main phone number as the outgoing number. However this number is not a DID with the SIP. I'm trying to set a outbound Rule that if by chance 911 is dialed that the outbound Caller ID number is the actual DID number on the SIP so that its routed properly. My SIP has a 3 digit test number (933) to simulate a 911 call that gives the E-911 information and the proper PSAP. In the Caller ID outbound rule, I set the source 9(..), (9..), 9..), and the test is failing as it is not sending out the DID on the SIP, and continues to send the number is the Default Caller ID in the Caller ID tab. How do I set this up that if by chance 911 is called, or the 911 test number to override what is in the default Caller ID field in the Caller ID tab...

First of all this should assist of not seen already: https://www.3cx.com/blog/voip-howto/outbound-rules-a-complete-example/

It maybe something on the provider side also, this string explains a few points regarding 911:

Also you need to go to Go to Settings -> PBX > Emergency Numbers and add 911 here.

Hard to test this one however

I did set a outbound rule for 911, and the test number. I also set the test number is Settings > PBX > Emergency number, however I had to delete it, as I kept getting an error that said Call Forbidden by Administrator. My connection to my SIP is IP based, and as a result a code had to be appended when the call invite goes out that I have in the outbound rules. And since any and all calls in Emergency Numbers ignores any outbound rules, I had to delete it... But I need to override the Caller ID number that is set in default, in order for the test to work successfully... Right now since its not overriding the Caller ID, the Call may not get routed to the PSAP should 911 ever get called..

Please note that in order to be able to have a different caller ID send when a emergency number is dialled you will need to have a second trunk. Since you trunk is IP based it is easy to add a second trunk and create an outbound rule for that routes emergency calls from the second trunk that will use a different caller ID.
