How to communicate in H.263pp HD

Hi all,

 

One of our customers has Polycom VSX5000(Ver8.0.3) and SX20(TC7.1.4).

In default setting, VSX5000 could not display from SX20 any video so we disable sending H.264 on SX20

(xConfiguration Experimental CapsetFilter: "H.264RCDO;H.264NIL;H.264" )

 

Now they can send/receive video/audio without problem.

But when the SX20 calls other Cisco E/P(e.g. C40) , it uses H.263pp with poor resolution 512x288 even though we call at 1980kbps.

 

Is there any way to send/receive better video (HD or higher) in H.263pp?

 

Regards,

Kotaro

I'd strongly recommend that

I'd strongly recommend that your customer upgrade their Polycom to version 9 (and preferably to the lastest 9.0.6.2) of the Polycom VSX software.  We've had many issues previously talking to the older polycoms, but the majority of these were resolved folllowing an upgrade to at least 9.0.5.

Many of the Cisco compatibility documents also recommend these versions as the minimums required to be compatible.

Doing so will stop the need for you to dumb down your SX20 with the CapsetFilter and you'll then be able to talk to all your other deivces without an issue too.  The CapsetFilter should only be used for troubleshooting and as a last resort fix.

Another option, if your customer has one, is to use a bridge/MCU to dumb down the communications with the polycom when calling it, and not use the bridge when calling between the other devices.  We've done this for one external site we can't get to upgrade - whenever we want to call this, we call the bridge and get the bridge to dial out to that endpoint with a reduced set of codecs (no H.264).

Thank you Wayne,

Thank you Wayne,

 

Unfortunately, the customer can't upgrade their Polycom because the service contract for that has already expired, and they don't have any bridge/MCU either.

 

But as workaround, we will suggest them to save two configurations( H.264 setting, no H.264 setting) on their SX20 and change the configuration by remote as necessary.

ex.)

When they call old Polycom ===> Use no H.264 setting with CapsetFilter on.

When they call the others ===> Use H.264 setting with CapsetFilter off.

Service contracts for the

Service contracts for the VSX5000 are still available to be purchased (until 2016) so for compatibility and ease of use, they may wish to reconsider purchasing one for their device so they can upgrade to the 9.0.6.2 version and not need to remember to switch configurations.
