I've got an IPO500v2 (8.0.66) with 16 channels of a PRI and 10 IP9608 telephones. All my licensing is valid. The system keeps saying "Waiting for Line" but the smart jack shows no LOS. I am currently running a trace, not really sure what filters I need to set to get a good handle on what's happening. When I got on site today I didn't even have intercom DT. After a reboot it seems to work but this is not a viable option for the customer. Any ideas or questions that may give me an idea as to WTF is going on with this system. Thanks in advance.
