Re: [Linphone-developers] send and receive?

[Simon MORLAT]

Hello,

Using 2 threads for sending/receiving is fine. I think it is also 
possible to use one thread to do both operations, with receiving first.
I think you can use the same timestamp to pass to the recv and send 
functions, and increment it of 160 before looping.
