[Freeswitch-users] uuid_exists - does it still exist?

[Phillip Jones]

Yep - I built out a very simple test:

 string uuid = "12345678-1234-4321-123456789012";

 apiResult = fsApi.Execute("originate",
string.Format("{{ignore_early_media=false,absolute_codec_string='PCMU'}}[origination_uuid={0},origination_caller_id_number={1}]sofia/gateway/broadvox/{2}
&park", uuid, "2129996599", "6093693828"));

 Log.WriteLine(LogLevel.Alert, "Originate returns: {0}", apiResult);

 Session.Execute("park", "");

relevant log details:

2009-09-11 11:28:22.750000 [ALERT] switch_cpp.cpp:1130 Originate returns:
+OK 12345678-1234-4321-123456789012

uuid_getvar 12345678-1234-4321-123456789012 uuid   RETURNS:
3e1ef4ee-8e39-b841-a9a0-6ac997b56275

uuid _kill 3e1ef4ee-8e39-b841-a9a0-6ac997b56275 -ERR No Such Channel

However: uuid _kill 12345678-1234-4321-123456789012 RETURNS +OK and drops
the call.

I repeated the test and attached the screenshot. Be interested to know where
that 3e1ef4ee-8e39-b841-a9a0-6ac997b56275 comes from.

All academic - just for interest and better understanding.
