[Roman Bedros (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-26643?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Roman Bedros updated ASTERISK-26643:
------------------------------------

    Description: 
h4. Symptoms
DeviceStateChange AMI Event contains an extra new-line character in the Device field after restart of the Asterisk.

h4. Steps to reproduce:
# Add a custom device state from CLI:
{{devstate change Custom:test INUSE}}
# Restart Asterisk
{{service asterisk restart}}
# Connect to Asterisk via AMI
{{telnet XX.XX.XX.XX 5038}}
# Login
{{Action:Login}}
{{Username:xxxxx}}
{{Secret:xxxxx}}
# Request device states
{{Action:DeviceStateList}}

Asterisk replies by the following messages:

{quote}
Response: Success
EventList: start
Message: Device State Changes will follow

Event: DeviceStateChange
Device: Custom:test

State: INUSE

Event: DeviceStateListComplete
EventList: Complete
ListItems: 1

{quote}
There is an extra empty line in DeviceStateChange event message.
If step 2 is skipped, Asterisk responds without an extra new line.

h4. Patch
A patch (attached in a comment) which fixes this issue was created, but I'm not sure that it doesn't break anything else.
