Hi there:

The wiki states:

uuid_exists
Checks whether a given UUID exists.
Usage: uuid_exists <uuid>



However when I call via an API call I get:

INVALID COMMAND!

I also don't see it in MOD_COMMAND.C


Has it gone?


Thanks


Phillip Jones.

You're not on the latest SVN that was recently added.

As a workaround or if your are unable to upgrade, you can use
"uuid_getvar [some_uuid] thisVariableDoesNotExist"
("thisVariableDoesNotExist" is any variable you can think of, a valid
one or literally 'thisVariableDoesNotExist' Smile
You'll either get an error that this channel does not exist any longer
or "undef" for the channel variable.
The api will return "+OK" in case the channel still exists, and
"ERROR" in case it does not.

You could even do this:
uuid_getvar <the_uuid_you_are_checking> uuid

If it exists then the return will be the uuid. Smile

Although I must say I recommend this instead:
make current

Strangely - the uuid_getvar <the_uuid_you_are_checking> uuid workaround does not work for me.

This is the result of:

apiResult = fsApi.ExecuteString(string.Format("uuid_getvar {0} uuid", call.Uuid));
Log.WriteLine(LogLevel.Alert, "RESULT: uuid_getvar {0} is: {1}", call.Uuid, apiResult);

returns a different uuid?????

2009-09-10 17:12:26.953125 [ALERT] switch_cpp.cpp:1130 RESULT: uuid_getvar 54dd24be-b0da-684f-acee-38c7530b4c2b is: 1a0e83db-240c-ac4e-ae45-bf5d5b46f5c3

the passed uuid is vaild however:

2009-09-10 17:12:26.953125 [ALERT] switch_cpp.cpp:1130 RESULT: uuid_kill 54dd24be-b0da-684f-acee-38c7530b4c2b is: +OK

Can a call leg have two uuids??

As a sanity test, can you bring up a bridged call and run this test directly from the command line and compare the results to what's in your script?

What puzzles me is why you can't just update to SVN trunk to get
uuid_exists in the first place? Its going to be 1.0.5 the more people
we have testing the faster that happens.

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.
