Greetings.
I try to review the g722 voip call in wireshark.
Everything looks good in rtp stream from my side (i'm developer of softphone).
Codec runs on 16KHz but reports to timestamps and sdp as 8KHz.

Audio quality is good, it is interoperable with itself/*/grandstream phones.

However wireshark reports that 100% packets are "out of seq" and 99,6%
are "wrong timestamp"

I'm confused a bit. I tried review QuteCom's g722 call - the same
story happens.
Please give me advice.
