Hi Tech Electronics,
Yeah its pretty awkward, This is a Canadian First Nations airport - About 600km north of the City of Winnipeg with no roads to get there!
They are not technical and don't have any testing ability or equipment such as butt phones.
Unfortunately, it IS the inbuild LS ports too. So, I am going to get them to restart the system tomorrow. I am sending them detailed instructions on how to do so through the front panel of the PBX. I will get them to follow cables and check connections as well as send photos of the ports and bix connections to see if there is any damage or anything loose, but even if there is it will probably need a tech to go up and fix the issues next week.
I have tried calling the 4 lines and they all ring, but aren't answered and the night greeting doesn't kick in when it should - so it definitely looks like the lines are down somewhere. The provider says they don't have a problem, but I will check with them myself before booking a plane ticket!
We did have remote access when it was installed 4 years ago, but this no longer works - I think they have changed internet providers since then. So we really can't do much but reset the system and hope for the best. They don't have phones working now, so if the system actually dies they are no worse off than they are now I guess!!
