ok I ran out quickly while the wife was cooking tea lol,. thats me in the bad books, Good job this is not far away from home,
I have a resolution albeit poss a temp one.
I went to check on the power issue to see if its connected to this prob, Im almost sure that the smart rios were keeping the system up when i first took it down, I need to check that, To be honest I assumed that it was correct. This is the only job I have encountered smart rios and I thought that it was a good idea that the whole system could be powered from all the backup batteries in them. Will check all the power connections and see where the issue lies on that.
Ok back to my original issue. I thought I would see if the dialler actually worked while I was there, If it didnt then it would confirm that the board may need changing.
I changed over the pstn from the dialler ,I threw in my mobile number, dodgy account no for a test,and reenbled the line volt check. Then did a engineer test in comms. It dialled my mobile and sat waiting for a handshake, Never got one as my impression of dtmf tones are pretty poor, It redialled and same again as my impression had still not improved.
So I know that the dialler works so why the error, Dropped out of engineering mode and guess what, error cleared.
How long it lasts is another matter,
I can only assume that something has been wanting to dial out, No changes in the settings and no unusual activity in the log so what it was i dont know.
I have disabled all triggers for comms so hopefully if this lasts it will never happen again.
Home for tea now, Thanks for your help guys, Will poss look at the power issue but that will be billable as its not related to this so I dont think he will want me to.
Hopefully if someone is googling an answer similar to this problem it may help them.
