[Asterisk-Users] Nasty little incident ...

Just a wild guess....

When the two meridian links disappeared, the channel numbers
probably changed. Instead of channels 1 through 124, you probably
have channels 1 through 62 and your supporting dialplan (and other
channel specific items) likely don't match.
