Polycom 3XX Redirect on Register Message

I was expecting the 4.0.1B UCS software to properly handle RFC 3261 SIP 3XX redirect messages.

 

I am properly inserting the updated CONTACT header on the return SIP message, and yet the Soundpoint IP phones do not attempt to re-register to the new server.

 

Has anyone worked on this in the past?  Is there a way to accomplish the redirects as I would like to?

Hello Jo,

welcome to the Polycom Community.

The UCS 4.0.1 Admin Guide list's all the supported 3XX Scenarios on page 552:

The Feature Descriptions & Technical Notifications => here <= and the UCS Admin Guide contain explanations regarding these functionalities.

 

You have not posted any configuration changes that you made in order to support this feature so other users won't be able to advise you on anything.

Re: Polycom 3XX Redirect on Register Message

I did see that and that was encouraging.  However, this doesn't seem to work properly when the message type is REGISTER.

 

Here's the logs showing the packets.  I simply never see an attempt to use the CONTACT header's URI to register to a new server.

The last line:

 

Reg UAC Response: code 301 new Address 'sip:108.x.x.29:5060'

 

would seem to indicate that the Polycom is aware it's supposed to redirect itself, but that simply never happens.

 

Couldn't seem to see any settings that would influence how the 300-302 messages are handled.

Re: Polycom 3XX Redirect on Register Message

Hello Jo,

 

if you are sure that you followed the fail over guide and programmed the phone accordingly and are seeking support please contact your Polycom reseller to bring this to the attention of the Polycom support team in your region.

 

Alternatively you are more then welcome to wait for other community members to help you troubleshooting your setup.

 

Best Regards
