Customer had IP403 with 2.0 & 1 T-1 (MCI with 24 voice channels). The only short code that was set up for dial out feature was { ? . line group 0 }. Everything OK. Upgraded system to v2.1, added second t-1 card, and connected new PRI circuit, tried to set up a dial 8 group and send calls out PRI (line group 1). Calls in are OK, but unable to call out, and no D channel activity. I changed short code { ? . line group 1 } and calls did go , but digits (4, as defined by dial digit count in system )were passed as unrecognizable number to Telco. I tried other short codes, but those only resulted in no calls established (although these short codes worked for other line group 0 when configured). I changed dial digit count to 11, and calls do completed, but there is a delay until the timer (4000ms)kicks in for calls less than 10 digits. I know this is not right but it was the only way to get calls in and out. Thanks
