Troubleshooting E911 and ANI/ALI tagging
Had a bunch of fun today with getting the correct number tagged onto our 911 calls. Note: Some telco providers override your call ID number with the primary number for your PRI when you call 911. This is a problem if you have a central VoIP phone system that services two or more separate physical locations. Before 911 starts ignoring you altogether because of the incessant test calls, get your telco to allow you to present your own callID number to E911.
