[asterisk-users] Problems with MFCR2 and Meridian

[Moises Silva]

Arturo, the error does not says much really, just that either the
other end timed out expecting a response from you, or your end timed
out expecting a response from the other end :)

However, from my experience, it may be an error in your DNIS/ANI
configuration and/or an mfcr2 library error ( less likely but still
possible ). Anyway, you can lear how to debug this problems with this
little document I wrote:

Good Look and happy debugging! :)
