Mumble vs SOGo
A side-by-side editorial comparison of Mumble and SOGo — release velocity, themes, recent moves, and the top alternatives to consider.
Mumble vs SOGo: at a glance
What is Mumble?
Mumble's 1.6 reaches a second release candidate while 1.5 loses macOS binaries.
Mumble is a mature open-source VoIP client. The 1.5 line is in maintenance, and its sixth stable release, 1.5.939 in October, shipped without new macOS binaries. The 1.6 series reached its second release candidate on October 25, about eight months after the first, with unsigned macOS binaries listed as a known issue.
What is SOGo?
SOGo's 5.12 line keeps shipping security fixes, now with mandatory settings attached.
SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made most 2026 releases about security. v5.12.11 in September fixed password reset poisoning and several XSS injections, and made a SOGoPasswordRecoveryBaseURLs setting mandatory when password recovery is on, with a warning that the XSS fix may affect webmail display. v5.12.12 in October fixed another major vulnerability and now verifies LDAP TLS certificates by default.

Mumble
5.0COLLAB
Mumble's 1.6 reaches a second release candidate while 1.5 loses macOS binaries.
◆ Current state
Mumble is a mature open-source VoIP client. The 1.5 line is in maintenance, and its sixth stable release, 1.5.939 in October, shipped without new macOS binaries. The 1.6 series reached its second release candidate on October 25, about eight months after the first, with unsigned macOS binaries listed as a known issue.
◆ Where it's heading
Work is moving toward a 1.6 stable release, but macOS packaging is a recurring problem across both lines. Release notes are blog links, so the feed shows milestones rather than features.
◆ Prediction
A 1.6 stable release is the likely next milestone; whether macOS builds are signed by then is unclear.
SOGo
2.5COLLAB
SOGo's 5.12 line keeps shipping security fixes, now with mandatory settings attached.
◆ Current state
SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made most 2026 releases about security. v5.12.11 in September fixed password reset poisoning and several XSS injections, and made a SOGoPasswordRecoveryBaseURLs setting mandatory when password recovery is on, with a warning that the XSS fix may affect webmail display. v5.12.12 in October fixed another major vulnerability and now verifies LDAP TLS certificates by default.
◆ Where it's heading
Fixes are increasingly arriving with secure defaults that break lax configurations, first password recovery URLs and then LDAP certificate checks. Feature work has been absent since 5.12.4 a year ago.
◆ Prediction
Further 5.12.x security releases are likely; operators should expect more defaults that require configuration changes.
