SIP Notify Limitations - Polycom VVX500

Hello,

 

I have been working on a situation with a group of Polycom VVX500s on a Broadsoft platform. Each device is configured with 30+ BLFs on a VVX Paper Expansion Module. The call flow routes from a uniform distributed call queue to a simultaneous call group. This call group rings 20+ devices, which causes everyones' BLF indicators to flash as well as their phones to ring. The issue is that, seemingly randomly, when a call hits the overflow call group the phones become overwhelmed and pretty much become unresponsive until they are power cycled.

 

The issue seems to be just the pure number of SIP NOTIFYs that are hitting each phone with the BLF notifications as well as the calls hitting the primary line itself.

 

What I am looking for is any information or documentation on the maxmimum amount of SIP NOTIFYs or traffic that a VVX500 can handle.

 

Any information or insight into this is much appreciated, thank you.

Hello NRG,

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?

We are running a couple of the VVX500s on UC v5.4.3 while the vast majority are on v5.3.0.

 

The devices on 5.4.3 do not seem to be affected any differently than those on 5.3.0.
