The provider is Integra. They had huge problems a couple of weeks ago when they moved this location to their 'soft switch' which uses sip trunking behind the scenes. We had all that worked out finally and it was stable for a week or so.
Then they moved a bunch of people from one floor to another, pretty simple - just premise wiring more than anything. I did convert one phone from an ETR to TDL, but the other one was a TDL to TDL - different cross connects, no port change.
I busied and released the stations and that cleared the problem...for about two hours. THEN they couldn't make LD calls at all - local fine, toll free fine, no LD. So the customer power cycled the system twice and it was fine for a couple of hours.
Integra is seeing no errors, and I believe them; they have been very supportive and consistent throughout this process. Rebooting the Magix fixes the problem for a while, then it comes back.
I am downloading the system this AM, doing a convert and restore, and replacing their processor with a new one - I can't think of anything else to do (have already swapped the boards.) It seems like the system is unstable which is extremely weird. They are losing their minds (so of course I am getting screamed at, which is a great way to start my Thurs.) and I am scrambling for answers - so any suggestions would be greatly appreciated. Thanks.
