Hello,
all the headers must be in a single parameter, I see that you provide
headers one by one in the params array. Try:
jsonrpc_exec('
{
"jsonrpc":"2.0",
"method":"tm.t_uac_start",
"params": [
"INFO",
"$dlg(to_uri)",
".",
".",
"From:$var(testjon)\r\nTo:$var(testjon2)\r\nContact:$var(testjon4)\r\nContent-Type:
application/json\r\nContent-Length: 0\r\n"
]
}
');
Cheers,
Daniel
