After finally getting the ok to switch from analog DID trunks to a PRI T-1 I find I have a few questions that my vendor doesn't have answers for. We currently have a 911 t-1 to give out ani/ali info I asume and I am wondering once we cut to the PRI can I get rid of the 911 t-1? Our main switch is a Definity v9. Any help would be greatly appreciated.
