[Saken (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-30344?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Saken updated ASTERISK-30344:
-----------------------------

    Description: 
To make calls, we use ARI requests with Content-Type: application/json
Memory leaks when creating a channel with variables.

We tried 18.11.3 and latest  18.15.1 and 20.0.1 and all these versions are affected.
Steps to reproduce:
1. Run asterisk with MALLOC_DEBUG

2. Check memory allocation in json

    asterisk  -rx 'memory show summary' | grep json.c

3. Create a channel through postman

Example POST request with Body in JSON format:

http://asteriskhost:8088/ari/channels/create?endpoint=PJSIP%2F8707398****%40cusp&app=test&channelId=26&api_key=asterisk:asterisk

{ "variables": { 
"CHANNEL(hangup_handler_push)": "hdlr1,s,1", "callid": "38", "callbackdatetime": "2022-12-07 17:19:00", "priority": "priority", "phone": "8707398****", "clientid": "clientid", "agreementid": "agreementid", "CONNECTEDLINE(num)": "9013****", "linetype": "Outbound", "skillgroupnumber": "skillgroupnumber", "sourcesystem": "    ", "mode": "auto", "camptype": "auto"} }

4. Check memory allocation in json after creating channel 

asterisk  -rx 'memory show summary' | grep json.c
