In order to allows us to better understand the problem, could you
please provide additional information such as more details about the
way the "noise disturbance" sounds (e.g. there's some hissing sound or
clicking while you're talking or the playback seems to stop and start
thus making the speech hard to comprehend), the SIP Communicator build
number(s) involved, the operating system(s) and Java version(s), how
the conference is created, how may participants there are in it,
whether the problem is always present and reproducible or it appears
at times during the conversation and disappears seemingly at random,
whether you doing something else in SIP Communicator such as
scrolling.

Please don't reply to me privately, do it on the dev mailing list. I'm
forwarding the text of your reply there now. If you feel comfortable
having the recordings you sent me there as well, please reply to this
message with them.

Thanks for replying ,

I m using sip-communicator-src-1.0-alpha3-nightly.build.3088 and also
used its build 2957 but i m facing the same problem in both of them.
My operating system is windows xp and java version is 1.6. I have
created a conference call using create conference call which includes
2 participents along with me .i.e. one callee and two participents . a
noise disturbance occurs in this case. i am attaching the recorded
sounds to you . kindly check. the sound disturbance is too loud in
comparision to the recorded ones. please help me out.

thanks...

Shashank,

Could you please describe your call scenario? What server were you
using? What software were the other two participants using?

Thanks for your attention,

I'm using conference call button from the tools menu to create a conference
call.

I have go through it in two cases but same problem occurs :

case 1 : All the three participants using sip communicator

case 2: Two participants using sip communicator and third one using CISCO
Linksys IP Phone SPA962

server used in both the cases is Asterisk 1.2.14

please help.

Thanks Emil,

Thanks for your support . The problem is solved.
But i am looking one more help from your side. Can you please let me know
the hardware requirements for sip-communicator. May be it also creating some
problem.

again thanks a lot for your help.

know the hardware requirements for sip-communicator.

The more the better! :slight_smile: Especially if you are planning on making video
calls.

More seriously, we haven't made complete minimum performance tests so it
would be hard to set a limit. A 2 GHz Core 2 Duo with 4 GB RAM should
definitely be enough to get an optimal user experience. This is by no
way a minimum though. I'd guess that a single core 2GHz with 1GB RAM box
would probably also work. I wouldn't go any lower though.

Hope this helps,
Emil

Hi Emil,

I'd guess that a single core 2GHz with 1GB RAM box
would probably also work. I wouldn't go any lower though.

that's a pity since 1.6GHz is a quite common specification- even today. Netbooks run mostly on 1.6GHz Atom. And these devices are ideal to carry around and to communicate. (Actually - this is what I have my eee for) And once again: In most parts of the world, old equipment must do the job much longer as in the Golden West (tm) :-).

I'm planning to upgrade one of my home PCs by the end of the year and - as it is a station for websurfing, *communicating* and occational OpenOffice, one of these Nettops should be enough for almost everything.

With the voice latency problem on my eee pending, I hesitate to invest. Would SC make use of a Dual Core?

As far as only text messages is concerned, SC runs on an PIII 1GHz at decent speed. Only one can forget about any multimedia on such a box.

Is it true that most the multimedia handling is done outside Java by native methods?

Is there a chance to lower the specs a bit (not much :slight_smile: ) to fit popular hardware considerably expanding the user base.

Sorry for nagging :slight_smile:
Conrad

Once again, these were by no means accurate "minimum requirements" but
rather a recommendation: Most of the people using and/or working on SIP
Communicator have that kind of hardware so if you want to make sure you
get optimal performance, you may want to get something similar.

since 1.6GHz is a quite common specification- even
today. Netbooks run mostly on 1.6GHz Atom. And these devices are
ideal to carry around and to communicate. (Actually - this is what I
have my eee for) And once again: In most parts of the world, old
equipment must do the job much longer as in the Golden West (tm)
:-).

We never made a decision not to support Atoms nor did we ever determine
that they were unable of running SC. For reasons mostly related to the
priorities of currently active developers (and hence indirectly to
funding) we have simply not had the time to evaluate performance and
optimize SC for similar configurations.

I'm planning to upgrade one of my home PCs by the end of the year and
- as it is a station for websurfing, *communicating* and occational
OpenOffice, one of these Nettops should be enough for almost
everything.

It should indeed. We should just as well have echo cancellation, jingle
and ice support, gtalk compatibility, desktop sharing, pseudo tcp and a
bunch of other absolutely useful features.

I am not at all implying that performance or platform specific
optimizations are somehow less important. As a matter of fact, we even
discussed a possible round of performance optimizations just a couple of
weeks ago.

Right now however, most of us are struggling to finish other, higher
priority tasks.

With the voice latency problem on my eee pending, I hesitate to
invest. Would SC make use of a Dual Core?

We do not have dual-core specific code if that's what you are asking.
However, the general performance boost they give you should put you in a
situation that's more similar to the systems that SC is known to work
well on.

Note that we never did determine for sure exactly what was causing the
latency issue on your system. I'd suspect that the lower performance
caps are simply surfacing issues that would otherwise appear less often
or not at all. What I am saying is that the problem is probably more
complicated than simply: you don't have the CPU power to handle audio
and video encoding together.

As far as only text messages is concerned, SC runs on an PIII 1GHz at
decent speed. Only one can forget about any multimedia on such a
box.

Is it true that most the multimedia handling is done outside Java by
native methods?

Yes. With the exception of some audio codecs (e.g. PCMU and PCMA)
Audio/Video grabbing, rendering and [en|de]coding all happen outside
Javaland.

Is there a chance to lower the specs a bit (not much :slight_smile: ) to fit
popular hardware considerably expanding the user base.

Absolutely. I expect this to happen in the following months (unless of
course we obtain contributions earlier).

Sorry for nagging :slight_smile:

Not at all. Thanks for your support and patience!

Emil
