[Kamailio-Devel] Kamailio for commerical use

[Kavita Rai]

Hi,
Thanks for the clarity. What is MI and SEAS interface? Can u please provide a link where I can find more about this. I checked the Kamailio documentation, but could not find anything related to these interfaces.

>>" If you write your own modules that link to Kamailio through the binary API, then they will be licensed by GPL "

The phrase "link to Kamailio"  would mean if we link Kamaillio as a shared library to our software and access its APIs, then its an issue.. we become GPL'ed .

Regards,
Kavita

Just remember that that part of the source will be licensed by GPL.

The question here is how your product integrates with Kamailio. If you  
write your own modules that link to Kamailio through the binary API,  
then they will be licensed by GPL. If you use the MI or just SIP, they  
propably won't.

I realized that we have other interfaces, the SEAS interface. Maybe  
it's time for the developer team to clarify their view of the license  
situation with MI and SEAS.
