Here’s how you can make and receive Skype calls from Asterisk without purchasing Skype for Asterisk from Digium. We’ll use stsProxy and SipToSis. The main benefits of this method is that you can access Skype as a normal user, you don’t have to create a business user for the SIP interface needed by Asterisk, and […]

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.

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 needed a solution for extracing mail files from big UNIX-style mailbox files, then parse them and extract attachments separately.
