I am getting a new PRI installed this month. The Telco has asked me to fill out a PRI check list. How should I have them set the PRI up. Specifically, Telco is Logix. I read the archives and all I see is B8zs, ESF, Custom. This seems to be too simple. I am a Nortel head...Please help. I know to change the ICOM number to the recieve digits to make the phone ring etc. Just the PRI set up is new for me. Thanks
