Re: Signalling Unregistered on CMA 4000

Hello Annunaki ,

welcome back to the Polycom Community.

It is always useful to include the currently used software version of all devices involved as issues experienced may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes.

You may want to utilize the CMA's build in Network sniffer to create a trace and try and troubleshoot the issue that way. Have a look => here <= for more details.


The next step would be to work with your Polycom reseller to get either them or Polycom support to look at the logs.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
