Tandberg MPS - Cucm/Cups client intermittant

[domstevens]

Hi

We have low quality and random call failures when calling to a MPS MCU registered with H323 -

So the strategy was to convert to SIP trunks.

We are failing to get CUPS working to a Tandberg MPS MCU, when we convert across to SIP

CUPS -> CUCM -> VCS -> MPS

The VCS has

a neighbour zones to CUCM and

a neighbour zone to MPS

Does anyone have any config examples, of restricting the bandwidth

it seems to request 384 k but get offered 1920 k

Best regards

Hi Dominic,

Before saying thing we need to know more about your setup. Like what kind of zones and subzones you have on VCS??

Based on that you can use link and pipes to limit the bandwidth.

But as i said please provide additional details for subzones and any  pipe or links you are using?

Please check below link for more information.

Page 202 onwards for bandwidth control.

Thanks

This is where the problem lies,

When the MPS is registered with h323 - we can apply a subzone bandwidth limit (768k), and can (mostly) complete calls but with low quality.

When the MPS is changed to be a SIP neighbour (zone and search rule) it does not appear to valid to control bandwidth

between two external zones -

It appears -  links and pipes can only be used between

- a zone and subzone

- a subzone to subzone

But not zone to zone

ie

Cups call from CUCM (8.5)  ---> sip trunk  --->  VCS  ----> sip trunk -----> MPS MCU

Are there any examples of applying bw control zone to zone,

And any tested versions of CUPS, CUCM, VCS and MPS with operational video ?

Hi Dominic,

What is the VCS version you are running in your setup?

cheers
