Has anyone even seen an intermittent issue where an 8 SLI and/or 16 SLI intermittently does not provide a power down (battery drop) when a CO line hangs up on an iDCS500R2 ?

System CO connection is via PRI and about 80 - 90% of the time the battery drops as it should on the SLI ports when the calling party hangs up. But every now and then it doesn't leaving our devices off-hook requiring the device to be powered down or unplugged to reset.

If you get on the circuit with a set you can hear the alternating high/low call dropped/hung up tone from the switch.

Power down timer has been increased to 5 seconds in an attempt to fix the problem to no avail.

All ports have power down option enabled, installer is stumped, Samsung even visited site at installer's request, still no luck even tracing back the root of the issue, whether it is coming from the switch or possibly the PRI, or maybe the SLI cards.
