Hi

It seems that to VPN provider does not accept the USER INFO message in receive call state
I don't know about your provider, but mine specify that USER INFO is accepted only in 2 cases, and none of them is regarding diversion on no answer.
It could also be a problem regarding the identification of the calling connected number, but I doubt regarding the cause of the release.

The best way is to request /// to remove the Message USER INFO in call state N4 ;
N4 mean that the network has receive and indication that the calling party is reached (ALERT) but no other answer (CONNECT, DISCONNECT, RELEASE...) has been received for a outgoing call.
This is tricky and I knew how to perform it in the past in the MESSAGESENCTRL table, but know ....if anybody else to how to perform, I would be great to refresh my memory and solve the problem of CNHUI

Hi,

i don't know if your problem is already solved.
as fouesnant already wrot the User Info Message is not supported from your provider. this is a very common behavior , at least in europe. the provider mostly don't support UUI2 . UUI2 is a user-user-service after the alerting. if you change the vari to =04480000, maybe you get success now with diversion on no answer.
but this will cause a new setup from the system where the diverted party is in! this causes also some different behaviors regarding the display info at the calling party side. there is no update about the diversion is executed, but it should be done.
good luck
