Here’s how you can record calls to mp3 files with Asterisk. Insert these to extensions.conf: 123456789[globals] MONITOR_EXEC=/usr/local/bin/asterisk-wav2mp3 [macro-record] exten => s,1,Set(CALLFILENAME=${STRFTIME(${EPOCH},,%Y%m%d%H%M%S)}-${MACRO_CONTEXT}-${DIALEDPEERNUMBER}) exten => s,n,Set(POSTFIX=$["${CALLFILENAME}" =~ "\/([0-9a-zA-Z#_\-]+)$"]) exten => s,n,Set(CALLFILENAME=$["${CALLFILENAME}" : "([0-9a-zA-Z#_\-]+)"]${IF($[${LEN(${POSTFIX})}=0]?: _${POSTFIX})}) exten => s,n,Monitor(wav,${CALLFILENAME},m) Recording start example: exten => 555,1,Dial(SIP/1234,,M(record)) The script asterisk-wav2mp3 can be downloaded here. Make sure it’s runnable (chmod +x asterisk-wav2mp3). […]

If you have 2 or more outbound lines, and want to prioritize them, use this macro: 1234567exten => 1234,1,Macro(dialWithFallback,555666) [macro-dialWithFallback] exten => s,1,Dial(SIP/line1/${ARG1}) exten => s,n,GotoIf($["${DIALSTATUS}" = "CHANUNAVAIL"]?tryLine2) exten => s,n,Hangup() exten => s,n(tryLine2),Dial(SIP/line2/${ARG1}) In this case, 555666 will be called first on line1, and if it fails (channel unavailable), it will be called using […]

On-demand MP3 streaming

The problem: small upload at home (ADSL, 80kb/s), big FLAC files on HDD, serve them via www so a remote client can play them realtime – solution: on-demand mp3 streaming, which automatically converts FLAC file streams to MP3 data. So if a client wants a FLAC file from the webserver, it returns the file in […]

I wanted a script to automatically watch for new emails, get the sender, subject and attachments from them, move the attachments to a directory and insert sender/subject info into a MySQL database. I needed a solution for extracing mail files from big UNIX-style mailbox files, then parse them and extract attachments separately.
