This is really strange... I upgraded a 406v2 from 3.2(55) to 4.1(12) now we cant make any LD Calls over th PRI, Group 0. I can see the call recognize the shortcode in monitor then it grabs channel 23 then says "CMARS SET TO OUT OV SERVICE"... But everything is set to IN SERVICE. My ARS table is correct, my system short code is correct. the service provider says the line is good. i can get incoming calls. Our tech support provider has sent it up to Avaya, but I really cant wait untill Monday for an answer....
