[sip-comm] license issue


#1

Hi All

I was looking for a SIP client for use with a commercial product. For
SIP Communicator is said to be licensed under Lesser GPL, it seemed to
me it would be a good option. However I browsed the SIP Communicator
site and found:

http://www.sip-communicator.org/index.php/Documentation/ZRTP4JMessageCodes

It seems that SIP Communicator contains GPL covered library. Bundling
such a library with LGPL-ed software violates GPL. It is permitted to do
the opposite of course.

I cannot find the source code for this zrtp4j library, so I cannot
confirm that it is really GPL and not LGPL covered.

Can anyone dissolve my doubts?

Hey Tomasz,

There was indeed some confusion about ZRTP related classes some time ago
but Werner fixed that. The wiki page must have left behind accidentally.

Fixed now.

Cheers,
Emil
