Hi Saul,
If the variables (of pjmedia ports) are local, it is impossible to
access them to stop the ring.
Furthermore, the caching pool will produce leak (not release-able).
And I think it is more efficient and easier to maintain only single
instance of pjmedia_endpt and pjmedia_snd_port for the whole
application (perhaps also the wav player port).
So yes, (member of) global variables should be better.
Regards,
nanang
