  VVX Expansion Color Module with 4.1.6 BLF Issue
  ‎01-23-2014 01:32 PM
  I recently have been having issues with a few VVX500's with the new Color Expansion modules running 4.1.6 firmware. I have been having an issue with the phones going into an infinite reboot loop and showing "Uploading 1 of 2 Core Files". I finally have discovered this occurs when I exceed 40 Line appearances which pushes into the second page of the Expansion module.
  I would provide a log file but the only way I can get the phone out of this infinite loop if to factory reset it. Any suggestions on why this may be occuring and a potential resolution?

  You should bring this to the attention of your Polycom reseller right away so they can raise a Support ticket with our team.
  Please ensure that you utilize FTP for provisioning and allow write and append so the phone can upload it's core dump.
  was there ever a resolution for this? I placed one at a customer site with 40 blf's. The customer added 20 more blf's and the phones went into the loop described above. Further, when we stripped it down to 20 blf, the phone slowed to the point where you could not transfer or disposition a call. It was several seconds to minutes for the phone to process anything.
  I am not aware if mmcdevitt60 followed up my advise but you would require to contact your Polycom reseller in order to provide the data to our support team.
  There are some restrictions when using BLF's that depend on what kind of BLF is being used (Attendant URI or individual attendant) and also if the monitored phones are part of a hunt group so BLF's would show multiple phones at the same time as ringing.
  Please work this via your reseller so one of our support teams around the world can check the provided data.
  Today I received a formal technical bulletin regarding this limitation. See attached.

  The Engineering Advisory 91820 documents the BLF usage with a BroadWorks call control platform and may not be applicable to the follow up posters setup or yours.
  It does explain the best practices for implementing systems where multiple phones are deployed as members of a Hunt Group, or in Busy Lamp Field (BLF) configurations which should be applicable to all call platforms but I still advise to raise this individually.
  The facts of the Advisory apply to Asterisk systems as well is my point. There is no ETA for a resoution to this limitation per Polycom support engineers. Just trying to provide Captain where this limitaion stands.

  Polycom support engineers resolved the 50 key limitaion with firmware 4.1.7. This firmware is also now accessible from the phones GUI interface.
  UC Software 5.2.0 added additional BLF enhancements. Please check the release notes for more details.
