[cisco-voip] IPVC3511, does it suck? or is it me

[Voll, Scott]

I'm not sure about the 3511 but we have an old 3510 and depending on the code it would do the same thing depending on what endpoints conferenced.  we were running a code version that was not the newest just so it would support the three different vendors.
 
I have also see this same thing if one stream is bad it can cause the whole conference to look bad and in really bad streams cause a complete reboot.
 
Just my 2 cents
 
Scott

I am very hesitant to purchase the 3511 with EMP, as it is twice the
price.  Will I have to have both the 3511 and 3511-E, or is it enough to
just buy the 3511-E? In addition, I am sorely disappointed with the 3511
w/o EMP, and have yet to hear from someone who has had a good experience
with the 3511. Anyone?

To answer your questions, the 3rd party joins via ad-hoc, and the video
quality immediately gets bad. When the 3rd party is on video with the
voice activation, the quality gets even worse.

I have checked the duplex settings and they are set to 100Mbps/Full
Duplex. Should it be something else?

Is there any other settings I should be looking at?

Thanks,
Avidan

Hello Avidan,

Without an EMP you can't have continuous presence conferences, just
voice
activated.

What do you mean on " the second a 3rd party shows up"? Does the 3rd
party
show up in the voice activated way?

Also for VTAs the EMP provides increased display quality because it has
enhanced H.263 codec support. I also recommend to use the latest code on
your MCU, and double check duplex settings.

I have an IPVC3511, and I'm using it as an MCU for all my VTA's, so I
have
it just set up as a SCCP mcu,

But, its doesn't allow for all the videos to be on screen at once
(continuous presence requires 3511-E they tell me).

When I do create an ad-hoc conference with meet-me, the second a 3rd
party
shows up, I get terrible resolution problems, the artifacting is
atrocious,
and the video is basically useless.

Does this sound like I have misconfigured the MCU (all 3 callers were on
the
same 10/100 network)?

Or, has anyone found that the IPVC is just a rebadge that just isn't
ready
for prime time?



Thanks,

Avidan
