[asterisk-users] Problem with a TDM400P

[Rich Adamson]

Seems to me that someone posted something about unusual analog 
connections in the UK that required a jumper wire (or something like 
that) on the pstn analog connection to the fxo port jack. (I'm in the 
US, so don't have a clue what I'm taking about.) Might be worth doing a 
little more google searching on that thought.
