Hello Yashpal,
you did not fully answer Kendo's question nor provided sufficient information.
- Can any other non Polycom End Point or Polycom End Point call you successfully ?
- Did you verify that the Lifezsize is running a supported / interoperability tested Software Version?
Please check the Release Notes => here <= and I would suggest to use at least HDX Software 3.0.4 or 3.0.5 if you require Support from Polycom
- Is this a SIP or H.323 Call?
- Have you checked the HDX logs to check for any errors
- Have you attempted a wireshark trace on a spanned port to verify / compare between a good call and a bad call
- Did your far end Partner contact their Support Organization and / or can they call any other Non Polycom Endpoints or the Polycom Test Sides?
As you can see by above follow up that troubleshooting should require some in depth testing and you may need to involve your Polycom reseller to raise a ticket with Polycom support if non of the community members have any more advise.
Best Regards
Steffen Baier
