IP 335 with Juniper EX switches

[JM]

We have about 120-140 Polycom 335 IP phones distributed across a Juniper EX4200-48PS Virtual Chassis [aka stack] running JUNOS 12.3R7.    The switches are configured with dual 930W, a power budget of 740W, LLDP and LLDP-MED at the interfaces. Switch with the highest populariton of phones has only used 125W. 

Intermittently, we lose an entire switch of phones for no apparent reason.  The switch does not lose power or reboot, it just seems to lose connectivity to all of the phones on 1 switch.  We have upgraded code [twice], logged everything possible to match timestamps for outages, basically exhausted all we know with the switches.

So, I am wondering if anyone else has experienced simiar symptoms using 335/550 and Juniper switches.

Hello JM,

welcome to the Polycom Community.

UC Software 3.3.3 is no longer a supported Platform so I advise you to upgrade to the latest UC Software 4.0.8

The community's VoIP FAQ contains this post here:

If you still experience issues after this you may want to work with Jupiter support and also involve your Polycom reseller so they can raise a ticket with Polycom support.

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