About the same problem here since CU 10.
Internal transfer coming from internal working on Polycom VVX.
Internal transfer coming from external failed on Polycom VVX.
Internal transfer coming from external on SfB Client (When VVX Unpaired) is working.
Updated Software version on VVX 501 to last.
Updated btoe connector to last.
No change.

It is now under investigation by Microsoft at least:
I have the same kind of message from SfB:
(SIPStack,CCryptoServiceCng::GenerateAndCompareHash:CryptoService.cpp(2637)) ( 0000001AB9AFB5D0 ) Exit - hash doesn't match. Returned 0xC3E93C14(SIPPROXY_E_SIGNATURE_INVALID)
(SIPStack,CCryptoServiceCng::HashAndCompare:CryptoService.cpp(2566)) ( 0000001AB9AFB5D0 ) Exit. Returned 0xC3E93C14(SIPPROXY_E_SIGNATURE_INVALID)
(SIPStack,CCryptoModule::RouteCryptoHashAndCompare:CryptoModule.cpp(914)) ( 0000001AB8154770 ) Exit - verify failed. Returned 0xC3E93C14(SIPPROXY_E_SIGNATURE_INVALID)
(SIPStack,CSIPRequest::ValidateRouteHeaders:SIPRequest.cpp(7093)) ( 0000001AB902E250 ) Exit - route set signature is invalid. Returned 0xC3E93C14(SIPPROXY_E_SIGNATURE_INVALID)
(SIPStack,CSIPRequest::VerifyIncomingRouteHeaders:SIPRequest.cpp(2302)) ( 0000001AB902E250 ) Failed validating route headers
So something is dodgy between SfB and Polycom VVX since CU10...

@patrick1900 indeed it is. Thanks for the notification post. CU10HF1 should take care of the issue (I've tested and confirmed it did in my lab). If there are additional issues post install, we recommend opening a support request with Microsoft Support.
