IMPORTANT: Server License users need to upgrade their ISL Conference Proxy to 4.2.0 or later to avoid Windows blocking ISL Online applications on Windows 7 and higher due to Microsoft SHA-1 deprecation policy.
As you might know, the IT industry is moving from SHA-1 encryption to a vastly more secure SHA-2 cryptographic hash function, which is used for digitally signing applications. Effective January 1st, 2016 Microsoft is no longer supporting applications signed with a SHA-1 code signing certificate.
SaaS users do not need to worry
ISL Online team has been preparing for this migration for several months. We added double signing support to ISL Conference Proxy 4.2.0 on June 4th, 2015. Since then, all ISL Online applications are signed using both, SHA-1 and SHA-2 hash functions. So, our Hosted Service users do not need to worry and won’t feel the transition to SHA-2 as we have upgraded our ISL Online Network some time ago and all is working properly.
Server License users need to upgrade to ISL Conference Proxy 4.2.0+
Server License users already running ISL Conference Proxy 4.2.0 or later will be able to use ISL Online services without any interruptions just like SaaS users. However, it is important for all other Server License users to upgrade their ISL Conference Proxy to version 4.2.0 or later.
While Server License users with a valid Extended support service (ESS) can upgrade their ISL Conference Proxy immediately, Server License users with an expired ESS will first need to purchase the yearly “Updates and Upgrades”, which account for about 15% of their license value.
