 I have SoundPoint IP 450 phones running SIP version 3.1.3 and 3.3.2 software.  When the phone connects to the system the MWI works correctly and a packet capture shows the phone subscribing.  After several days the phone stops subscribing and the MWI stops working.  What makes the phone stop subscribing and how do I correct the issue?

Hello rfoley,

welcome to the Polycom Community.

Is this SIP 3.1.3 and UC Software 3.3.2 or BootROM 3.1.3 and UC Software 3.3.2?

 

UC Software 4.0.9 is currently the latest supported Software for the SPIP450 range so could you kindly upgrade and monitor the phone ?

 

Any MWI issue after this can then be troubleshoot by Polycom support once a case is raised via your Polycom reseller.

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

Best Regards

The SIP software version is 3.3.2.0413 and the BootROM version is 4.5.0.0083.  There are several sets running SIP software version 3.1.3 and I believe the BootROM version is also 4.5.0.0083.
