Reboot with VVX Expansion Module

[Anonymous]

Hi,

I have three VVX expansion modules and when I insert the keys blf (via web or provisoning), the phone restarts continuously.
All the 110 keys are configured.
The display shows this messages "Uploading 1 of 2 core files" and "Uploading 2 of 2 core files". The phone's firmware is 4.1.6.

Thanks

Hello Alessio,

welcome to the Polycom Community.

You should urgently bring this to the attention of your Polycom reseller and provide them with the logs and core files as our support team requires these.

You could in parallel send me the MAC address of a unit affected by this.

It may be worth taking a wireshark trace during adding the BLF keys so we can see the traffic all these BLF's are causing.

Polycom only supports 45 BLF Keys on the expansion module at this time.  Several resellers have open tickets with resellers and Polycom is looking into it, but the data sheet for the expansion module even states this.  So, for now, this is by design.  Reduce your BLF keys to less than 45 and it will stop rebooting.  You may have to format the file system on the phone if you can't get it out of the loop.

Hello Louis,

welcome back to the Polycom Community.

There is no official document in regards of BLF as far as I am aware.

There is a huge difference between the amount of supported active BLF's as this all depends on them being part of ring groups etc. 

This needs to be looked at individually and we cannot simply state that this is the case in the original posters issue.

Actually, I mispoke as I was recalling from memory.  The Polycom VVX Expansion Modules with Polycom VVX Business Phone Feature Profile 78960.pdf document clearly states that only 50 BLFs are supported with 3 connected VVX expansion modules.  I and other partners have easily reproduced this issue.  It has nothing to do with ring groups.   If I configure 50 BLFs on line keys, the phone and module go into this reboot sequence and won't stop until you factory reset the phone.  Judging from this document, this was by design, but severely cripples the use of the expansion modules.  Why would they produce a module with 84 buttons and limit the use to 50 BLFs?  Doesn't make any sense to me..unless the phones are so under powered that they just can't handle it.

Hello Louis,

as explained in this and other post before, we need to track this the correct and professional way so a service ticket with our support team is required.

I personally had not yet had any escalation in my EMEA region so far.

The sole purpose of an expansion module is not just to be a BLF but also to provide Lines, Shared Lines, Speed Dials or EFK's.

What yourself have found in the field may be a performance or firmware issue but without ticket and the relevant data I am unable to comment.

hi,

I am having the same problem, polycom vvx 400 + 2 vvx expansion modules.

the first module works fine, but when I configure BLF in the second module, it doesn´t stop rebooting, I have to restore to defaults.

any solution?

thanks

Hello Roger,

welcome to the Polycom Community.

I would suggest you test this using the latest UCS 4.1.7 Software as this has many enhancements for the Expansion Module such as:

92177 In a BLF scenario, the phone now displays all the statically or dynamically configured BLF lines (~50) when the expansion module is connected to it and no longer causes any issue.

Once you have done this and still face an issue in your enviroment please go ahead and work with your Polycom reseller and bring this to the attention of Polycom support.
