FAQ - Auto provisioning: Delay firmware upgrade/downgrade if there is an active call

From software 2.52 it is possible to delay firmware updates started via provisioning if there are active calls.

• By default firmware update does not check if there are active calls
• Via provisioning parameter the DECT device, delay firmware update up to <configured> times if there are active calls
• The delay time = 300 seconds
• When after the the n times x 300s there is still an active call the firmware update will be done and the active calls will be disconnected 
• The setting is per DECT manager

<?xml version="1.0" encoding="UTF-8"?>
<provisioning version="1.1" productID="e2">
    <nvm>
	<!--
          Set if and how often DM delays swupdate if any call is in-progress.
          dm.<n>.FwUpdateCallBlockAttempts = 0          => no check for calls in progress
		  dm.<n>.FwUpdateCallBlockAttempts = n (n > 0)  => delay up to n times, delay time = 300s
        -->
        <param name="dm.local.FwUpdateCallBlockAttempts" value="2" />
    </nvm>
</provisioning>

In syslog you would be able to see the following messages, in this example there is an active call.

• swupdate: Check if swupdate needs to be delayed due to active calls (call block attempts=2)
• swupdate: Active call detected...retry-count:(1/2), time=300 sec
• swupdate: Active call detected...retry-count:(2/2), time=300 sec
• swupdate: Starting update\n
