  • Version 3 on Ubuntu Linux doesn't support srv records for direct sip calls. Version 4 on Android does.
  • On Android, if you enable AVPF on an AAISP account then calls fail.
  • It's reported that earlier version of Linphone can be tricky to setup, where as version 4.2 (and above) is very much "it just works" after going though the account setup.

Click to call

There was a discussion about using a web based CRM system and clickable telephone numbers, (e.g. using tel://03333400999) and making it work with linphone, as at the time it was not working for the end user.

On Windows, it was suggested that if you like importing random .reg files from the interwebs, there's https://gist.github.com/mekegi/7951345

Firewall & Security

  • You will also want to set up firewall rules, as per the VoIP Firewall page.
  • Also see the VoIP Security page for information about securing your VoIP service.
