Phones FAQ

Why are the BLFs flashing on my phone?

If the lights which indicate the status of users on your desk phone (BLF) are not working properly, constantly flashing, or not changing, there are few reasons:

Some of the more common reasons might be:

  • The SIP ALG is not disabled.
  • Your network was experiencing a packet lost during a period, and some packets were lost.
  • The firewall was blocking the packets which made this kind communication

IP Telecom recommends that you verify the Minimum Network Requirements are in place on your network and reboot the phones to try to resolve the issue.

If the problem persist after rebooting the phones, please contact us to reboot the BLFs.
