today I've tested jitsi a lot with 2 Windows Computers in a local LAN and
found some strange issues:
Registrar less SIP:
1.There is no presence info, although chat, call and video works.
2. Sound Quality: One of the 2 PC's has an audio output Problem with jitsi.
When ringing or during the call it sounds like the output is closed to be
immediately open by the next sound, this producers an annoying crackle.
Since the Audio output is default connected to a SPDIF output this is heard
very clearly. Using a different Sound output (with less good quality) this
is far less annoying. There is no problem on this PC with other Programs
with Sound output. This audio problem is particular bad when using registrar
less sip my subjective feeling is that it gets "better" if connection goes
SIP via iptel.org:
3. the audio stream is going via the iptel.org server. My understanding
was, that the audio stream will connect directly between the 2 PC's.
I have a alg sip firewall between the LAN and internet (Cisco ASA) but in
this particular case this should not make a difference.
Jingle Test: Two account's on jabber.org trying to connect via jitsi:
4. Only chat is possible. I see no presence information and (maybe
therefore no buttons to call or video or screensharing)
5. found email@example.com , I'm getting presence info, I
can get called, BUT no videome.
Can you please help?
