Good Morning all,
I've
been doing some testing with Opal - specifically with the SimpleOpal
application, and have found a problem connecting to Tandberg (model
880). It seems if I set up a call between the two endpoints, I don't get
video displayed on the Tandberg. I get video from the Tandberg to
SimpleOpal, but not the other way around. After about 33 seconds, the
Tandberg displays a message - "Temporary network failure", and the call
drops. It doesn't matter whether the call is out-bound, or
in-bound, the behavior is the same.
I've
tried 3 different version of the Opal code; v2.2.2, v2.2.4, and v2.3.1.
and they all exhibit the same behavior. I am building and running on
Windows XP with Visual Studio 2005. This is the first H.323 endpoint I
have seen this issue with. I've successfully connected to several
different Polycoms and Netmeeting endpoints without issue.
I did a bit of digging, and
I've seen a compatiblity issue mentioned in the list archive by Craig Southern
and Simon Horne about the ASNParser and the videoBadMBsCap flag in the
capabilities. But I didn't see what the symptoms of this issue
were. Is this the same issue?
One more piece of information; I enabled logging on the Tandberg during
the failed calls and see a message "eventHandler Unknown mediatype 0"
repeating over and over - at roughly the video frame rate.
Does any one have any information on this issue? A cause, a
workaround? Any help would be appreciated.
Thanks.
