[Asterisk-Users] [ot] Grandstream hardware

[Eric Wieling]

How does Grandstream become patent indemnified for their hardware?  I
would assume they did not pay for a license for G723,1 and G729 directly
to the patent holding company.  Maybe they did.  I always assumed the
indemnification came with a DSP that implemented the codec.
