Hi,
=20
I'm trying to build an application using ccRTP (1.6.2) and I'm having
some problems. My application is a SIP IVR application and right now I'm
using PCMU payload.=20
=20
In my -Thread and TimerPort derived- thread class's run() method, my
application is sending -30ms long (240 bytes)- audio packets to
destination and nearly for the half of the packets, my
-SingleThreadRTPSession derived- socket class's onExpireSend method is
triggered. When I sniff the network with Wireshark for UDP packets I
don't see the dropped ones and the sound is distorted on the destination
side.=20
=20
My code is nearly the same as the demo application audiotx.cpp except
the audio source mechanism.=20
=20
In the mailing list archives I've found a similar problem
(http://lists.gnu.org/archive/html/ccrtp-devel/2003-03/msg00000.html)
but the patch for this bug is already in my copy of ccRTP library.
=20
I'm using MS Visual Studio 6.0 (sp6) on a Windows XP Prof (sp3) machine.
=20
I'd be glad if you may help me.
=20
Sincerely,
=20
Eren AYKOC
