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.

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.
