SoundStructure C16 Line register issue

[Sang]

Hi,

We have a SoundStructure C16 interface with Cisco Unified Communications Manager. Cisco have 2 server to provide Server Redundancy function.

If we input both server IP address at C16 line setting page Server 1 and Server 2, then C16 cannot register the line at Cisco.

If either one of the Cisco server down, C16 success to register the line at Cisco. 

If either one of the Cisco Server IP address input at the line setting page, C16 success to reigister the line at Cisco.

Seems like C16 cannot interface with Cisco which provide Server Redundancy function.

Anything we have missed to set in C16, so that we have the above problem?

Thanks.

Hello Sang,

welcome to the Polycom Community.

It is always useful to include the currently used UC Software version as issues experienced or a question asked may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Read First"

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here

I suggest to create a DNS record and register both Subscriber addresses that way.

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