  • Trouble configuring asterix for home pbx with IP phone
    Retrieve the official files from asterisk.org, extract and change directories. Source: almost 2 years ago
  • SIP server installation
    Perhaps asterisk / FreePBSX or similar would suite your goals? asterisk.org. Bit of a learning curve, but there is lots of documentation and examples too. Source: about 3 years ago
  • Looking for a Simple Texting Service
    Asterisk? Foss telephoniserver, been around for a long time so mature and solid https://asterisk.org. Source: over 3 years ago
  • Phone Scammer group's open directory
    These are all just sound files, and from what I can recall I'd bet at least 97% are the standard Asterisk (open source PBX software) set (probably core perhaps plus some extras en + es for some). -- It's certainly Alison's voice, and and all the same jokes are there (e.g. zombies, lotso-monkeys).

  • RTP Module in Opensips
    Did you have some tutorials / Websites / videos ( other than https://opensips.org/ ) of how we can intégrate these modules please ? Source: over 2 years ago
  • Send DTMF digits during call?
    So I finally got a SIP connection working, not through my own server (which uses a non-standard port number for SIP) but through OpenSIPS. Source: over 2 years ago
