I was told that I should contact this mailing list in hopes of
finding out why SIP Communicator doesn't work for me.
I've used SIP Communicator in multiple environments, including
Windows 2003 and Windows XP Professional. I'm a heavy user of
Java, so I almost always have the latest version of Java on all
the systems that I use. In the configurations that I've used,
the primary audio devices and secondary audio devices all appear
to work properly in other applications, but when I use
SIPCommunicator to initiate a loopback test to my SIP provider, I
don't hear any audio output on any devices.
The last version of SIP Communicator that I used was
1.0-alpha3-nightly.build.1905, but I have used previous versions
as well. None of them have worked properly for me; I wasn't able
to hear the audio from the remote party in any version.
Audio output through the Java sound libraries on at least one
system has been verified to work properly though JAMP. The audio
devices that I am using include CMedia's CMI8738, RealTek/Intel
HDA ("Azalia"), a SiS USB audio device, Microsoft LifeChat LX3000
USB audio, Microsoft LifeChat ZX6000 USB audio, and a Yamaha PCI
Other tests that I've tried include calling my voicemail number
(the call succeeds, but no audio is played on my end) and calling
myself (the audio device rings, so playback is OK). Other SIP
UAs work fine on the same machines with the same hardware (I use
SJPhone and Xlite primarily).
I am located behind a NAT in all configurations, but my
SIP provider's proxy provides adjustments to SDP messages so that
all RTP streams are relayed through their servers. My SIP
provider is Voxalot, and I am using proxy01.us1.voxalot.com until
probelms with the other proxies are corrected.
I have tried both the DirectSoundCapture option as well as
JavaSound audio capture option without success in SIP
It was suggested that I create a Wireshark capture to attach to
this message. The capture has been bzip2 compressed and attached
to this message. A UDP-only filter was applied in order to
reduce the noise from running a Remote Desktop for another
machine. Other information is available on request.
Please keep me in either the To or CC fields when sending a
reply. I don't monitor the SIP Communicator mailing list.
