BlindTransfer with AMI Issue

Hello,
Im trying to test a AMI Action BlindTransfer.
But when i send de action return the error:

Response: Error
Message: Transfer invalid

My objective is make a transfer to external number, but a tried to another internal endpoint too and i got the same error.

I already turn on the manager logs and debug but no error abount this command is displayed.

Im using Asterisk 15.7.2 for thist tests.
My objective is just compare the comportament with de Dialplan Transfer application.

The command:

Action: BlindTransfer
Channel: PJSIP/0000-abced
Context: test
Exten: sip:11111111111@sip_trunk_0

The sip_trunk is available.

Have you guys a suggestion to make this work?

Provide an extension, for the extension parameter, not a URI.

I already did this test, but the same message is displayed.

My test context is very simple:

[test]

exten => _x.,1,NoOp(Testes Refer ${CHANNEL} - ${CHANNEL(name)} - ${UNIQUEID})
exten => _x.,n,Answer()
exten => _x.,n,Hangup()

exten => h,n,NoOp(Exten de desligamento)
exten => h,n,Hangup

Command with real data:

Action: BlindTransfer
Channel: PJSIP/8218-002f82eb
Context: test
Exten: 1234
Response: Error
Message: Transfer invalid

I suspect you are trying to use this on a channel that isn’t bridged, and should actually be using Redirect.

You right david551, after bridged the channel the transfer was successful.Thanks
