Hello Steffen, Looking at your post you say this is now fixed, however I have updated all my VVX400 phones to version 5.9.1.0615 from 5.6.0.17325 and are now seeing the below errors show up on all my FE's. is it possible for someone to have a look into this to make sure the issue is resolved and that this issue is resolved in all future releases ?
Error 14435/LS Protocol Stack: At least one invalid authentication signature was detected. There were 1016 messages with invalid signatures in the last 1 minutes. The last one was this SIP message: Trace-Correlation-Id: 3859812376 Instance-Id: 56B402C Direction: no-direction-info Message-Type: request Start-Line: REGISTER sip:FQDN SIP/2.0 From: ;tag=409b77048b;epid=f88c9031ac To: Call-ID: f19ca6e527244d2c969efd5ad4140689 CSeq: 2 REGISTER Contact: ;methods="INVITE, MESSAGE, INFO, OPTIONS, BYE, CANCEL, NOTIFY, ACK, REFER, BENOTIFY";+sip.instance="" Via: SIP/2.0/TLS x.y.z.107:54371;ms-received-port=54371;ms-received-cid=9366100 Max-Forwards: 70 Content-Length: 0 Cause: This could be due to a client or server which is not handling authentication correctly, or it could be due to an attacker. Resolution: None needed unless the failure count is high (>100). Check your network for any rogue clients. Restart the server if problem persists.
Please note that we didn't have these errors before we updated the Firmware Version. Regards Rony

Hello @RonyVI ,
welcome to the Polycom Community.
I am not aware of any issue and have not had this seen reported. Please get this into support.
In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.
End Customers are unable to open a ticket directly with Polycom support.
If this is some sort of an Internet discounter providing your MAC address or your Polycom devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Polycom device from.
If the unit is no longer within warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here
