CUBE initiates an INVITE after 480 Refer Failure

Hello,

I'm facing a problem where CUBE initiates two times INVITE after Refer Failure event with 480 Temporary unavailable.

The CallFLow is Bellow :

CVP sends Refer to CUBE --> CUBE transfert the REFER message to the ISP with Refer-to Header

the problem is, after CUBE receives 480 Temporary unavailable NOTIFY Message, it sends 2 times INVITES messages instead of transfering the 480 NOTIFY message to CVP to try another Refer.

Do you have any idea to avoid CUBE sending INVITE instead of transferring the 480 NOTIFY message ?

Thanks Community
