VVX 411 Call Transfer Failed

Dear Team,

I have configured VVX 411 with Skype for Business Server 2019 (7.0.2046.0). I am able to make internal and external calls. I can transfer an internal call to another VVX (blind). When a user received a call from outside and wants a transfer, the call gets disconnected immediately after pressing the send key. 

I am running UC version on VVX.


I have tested the same call with SFB Client and int works fine. 


Kindly requesting your assistance to fix this issue.

Re: VVX 411 Call Transfer Failed

Hello @a.kumbalakandy ,

Welcome back to the Poly community.

Some or a couple of your old post(s) or reply(s) to them => here <= are still open/pending as you have not marked these as "Accept as a solution" or at least provide some form of feedback or answer.

If they are in this state nobody finding them via a community search will know if an answer or advice provided was useful and has maybe helped you.

Could you therefore kindly go over them and mark or answer as appropriate?

If they are marked as "Accept as a solution" other users can find these easier and it helps them to utilize the community more efficiently. Please do not simply mark them without any type of feedback.


In one of these replies we also provided you with details on a FAQ that can help you to troubleshoot this and/or provide some meaningful logs:
