Hi, I?ve just started using Amazon S3 for storage and have used s3fs to mount the buckets on the file system. 1. I was wondering if anyone has a better method ? even though this meets my current needs. 2. if there is an automounter that could be tweaked to work with s3fs.

Hello I need Asterisk (1.4.39.2) to simulate a flash hook (ie. hitting the "R" key on European handsets) so I can put a call on hold, dial a second number, and set up a conference call. By default, linux/include/dahdi/kernel.h sets the flashtime to 750ms, which appears to be too long for European telcos, as they seem to expect a line cut of about 100ms. After editing the
