SIP Client/SDK Gold license

As you can see at the SDK and softphone pricing sections, our software is mainly licensed per server. The Basic license allows the usage with one single server and the Advanced license allows up to 4 servers.
However we also have a Gold license which is much more flexible regarding the licensing.
If you don't have your own limited number of SIP servers or if you are developing an app, which you wish to sold to others with freely configurable SIP server address, then most probably you should opt for a Gold license.

We still prefer to add some license protection (lock the usage with your servers or app) but with the Gold license there are many possibilities: 

  • 10 separate VoIP servers owned/controlled by you (10 IP and/or domain)
  • a whole subnet/24 (255 address)
  • a wildcard domain (allowing unlimited usage by creating as many subdomains as you wish)
  • server type (binding the license to your SIP server User-Agent/Server SIP header, thus it can be used on unlimited servers with this option)
  • main class name or executable name (for the Java SE/JVoIP library only)
  • app package name (this is possible with the Android/AJVoIP library only)
  • license key only (for selected/reputable companies only)
  • or another licensing based on our agreement

Contact us about the possibilities or if you are in doubt. We are open also for other solutions. The most important thing is that we would like to avoid unauthorized usage by publishing a license, which potentially can be downloaded or extracted from your software and freely used elsewhere.
