The Expressway-C now defaults to SHA-256 for signing SSO requests it gives to clients, and you can
change it to use SHA-1 if required. In version X8.5, when the SSO feature was previewed, the
Expressway-C defaulted to SHA-1 and there was no way to select a different algorithm.

Expressway-C defaulted to SHA-1 and there was no way to select a different algorithm.
Note: If you were using the SSO feature with X8.5, this change may cause it to stop working after upgrade
to X8.5.1. You have two options to resolve this: leave the new default on the Expressway-C, and you may
need to reconfigure the IdP to expect requests to be signed with SHA-256 (recommended for better
security); the other option is to revert the Expressway-C's signing algorithm to SHA-1 for your IdP (go to

Audio calls may be licensed as video calls in some circumstances. Calls that are strictly audio-ONLY
consume fewer licenses than video calls. However, when audio calls include non-audio channels, such as
the iX channel that enables ActiveControl, they are treated as video calls for licensing purposes.
