[asterisk-users] MOH Codec Issue - Fixed

I recompiled a version of Zaptel to no avail in an attempt to find a quick
fix. This did not help, however have since upgraded the box to Asterisk
1.4.13 and the issue has disappeared. As such I put it down to either being;
    1. Zaptel was broken, I should have however recompiled Asterisk after
recompiling Zap (Opposed to being impatient and frustrated), or
    2. There is a bug in 1.4.7. I haven't had time to try and reproduce it,
plus it would be a purely academic project as if there was a bug it has
since been fixed.

Thanks for the suggestions Paul.

Nick.
