[asterisk-bugs] [JIRA] (ASTERISK-22800) Dynamic parking pickup doesn't use PARKINGLOT

[Richard Mudgett (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-22800?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=211442#comment-211442 ] 

Richard Mudgett commented on ASTERISK-22800:
--------------------------------------------

Your log does not have the verbose level set high enough to show it, but from other provided information your parking lots overlap.  You are using the automatically generated pickup extens to retrieve the parked call.  The automatically generated extens specify which parking lot they pickup a call from in the parameter list.  Since they overlap, the generated extens overwrite each other.  If you set verbose level to at least 3 you will see this happening.

> When picking up a call from a dynamically created parking lot, specified with the PARKINGLOT variable, the wrong call is picked up.
> A full trace is attached. The call flow is:
> 1. External caller 0000101 called 0234567890 which routed to telephone 2000105.
> 2. Telephone 2000105 parked the call using #*7 on lot park_4, slot 701.
> 3. Telephone 1000102 called 1000101.
> 4. Telephone 1000101 parked the call using #*7 on lot park_3, slot 701.
> 5. Telephone 2000105 dialled 701 and got the call parked at step 4, which is the wrong one.
> The important part of the trace is:
