[asterisk-users] Indonesian MFC/R2

[Steve Underwood]

Hi,

There are problems with Indonesian MFC/R2. My software implements one 
version of Indonesian R2 signaling, but there are others. Some are very 
different from normal MFC/R2 signaling, and would require a considerable 
rewrite of he existing software. You need to find out a little more 
about the version of R2 you have.

You can find out a lot more about what is going on by adding 
"loglevel=255" at the beginning of unicall.conf. Then the logs will show 
the fine detail of a call's progress.

Regards,
Steve
