I am experiencing the same issue.

 

Mobile devices (iphones/ipads) calling in using Polycom Realpresence to HDX7000 unit does not seem to be getting audio/video.

 

Tried it with identical systems in other places and it works.

 

These connections were working before (2 weeks ago) and no configuration changes were made to the system/environment.

 

I gather from different forum posts that these could be due to firewall issues (not applicable in my case) or network settings - no changes made.

 

Any recommended settings we need to use?

Hello blacklung82,

welcome to the Polycom Community.

 

Can you describe what you mean by "Tried it with identical systems in other places and it works." ?

 

Lack of Audio /Video is 99,999999% of the time a firewall issue.

 

  • Did you try from other mobile devices in the same network (Wifi / Mobile Data)?

  • Are these devices using RPRM or CMA or is this standalone clients?

  • How can you be so sure that no network changes had been made?

I would suggest to start a wireshark trace on the HDX end via a spanned port and see what network traffic reaches the HDX.

 

If it is only signaling and no rtp then this kind of verifies already the firewall / network suspicion.

Hi Steffen,

 

Thanks for getting back to my question. Please allow me to clarify base on your response.

 

"Tried it with identical systems in other places and it works."

- Attempts on our local HDX system failed but was successful with another unit at a separate location.

 

Lack of Audio /Video is 99,999999% of the time a firewall issue.

 

  • Did you try from other mobile devices in the same network (Wifi / Mobile Data)?
    Yes we did. We tried different mobile devices on both Wifi/Mobile Data
  • Are these devices using RPRM or CMA or is this standalone clients?
    Standalone clients
  • How can you be so sure that no network changes had been made?

To clarify, no changes were made on the HDX unit as only a few of us have access to do so. As for network changes, I am unsure, but this unit is a standalone directly on the carrier's circuit if this makes sense.

 

I've tried some of the suggestions on disabling diagnostic mode but to no avail. Would be happy to try out any new ideas.

 

Thanks for your help.
