SX20 to Polycom HDX live call automatically convert to audio call

Hi Guys,

One of my client is facing below mention issue.

It's a fresh installation and while testing with other VC units (Polycom) we are observing some weired behaviour like

1.       Some of the VC calls are automatically converting to audio calls and only hear/speak, No video.

2.       Some of the VC’s, we can see them  but they cannot see us.

It's a complete P to P call dialing on IP, no signaling device involved in this call set up.

SX20 is ruuning on TC 6.0.1

All remote VCs are from Polycom HDX series endpoints.

Any specific configuration do we need to enable in SX20 like capset filter? or some other configuration you recommend to change at Polycom end.

Thanks in advance for your help.

Your question is better suited to the TelePresence section of the forums where similar issues between Cisco and Polycom devices have been discussed on many occasions.

I had previously expeienced issues talking to older polycom devices (VSX series) and these issues were resolved in TC6.2.1.

I can confirm that we have no issues with the latest software (TC7.0.2) on our SX20s talking to Polycom HDX devices running Release 3.1.1.3
