[asterisk-users] Help on strange problem...

[Johansson Olle E]

Stuart,
First update to the latest version of the asterisk you are using. When  
reporting problems, always
mention which version of Asterisk you are using.

If the problem still exists, please file a bug report with proper  
logging as described in the bug guidelines.
Thank you.
