Fourwaves vs rtpengine: at a glance
What is Fourwaves?
Fourwaves is polishing participant messaging after a pricing reset.
Fourwaves ships small daily changes to its event and conference platform. The past two weeks focused on participant communication — direct-message alerts, richer discussion emails, a communication Preferences page — plus account-page and domain-settings cleanup.
What is rtpengine?
rtpengine backports the same DTLS and socket fixes across four maintenance branches at once.
Sipwise's rtpengine media proxy is maintaining several release lines in parallel (mr13.5, mr14.1, mr26.0, mr26.1, mr26.2), and most recent entries are coordinated backports. The September 16 batch fixes hash-table updates, nested string lookups and stop_forwarding mixups across four branches, and adds DTLS negotiation corrections (setup=actpass logic, ignoring incorrect DTLS=passive, keeping TLS IDs on answer role changes) to the mr26.0 and mr26.1 lines.

Fourwaves
6.3MEETINGS
Fourwaves is polishing participant messaging after a pricing reset.
◆ Current state
Fourwaves ships small daily changes to its event and conference platform. The past two weeks focused on participant communication — direct-message alerts, richer discussion emails, a communication Preferences page — plus account-page and domain-settings cleanup.
◆ Where it's heading
The September 17 pricing change to yearly submission limits with unlimited events set the commercial frame; the product work since then makes ongoing participant engagement smoother. Direct messages are replacing older contact paths.
◆ Prediction
More notification and messaging controls for participants and organizers are likely, continuing the current run of small communication fixes.
rtpengine
5.0MEETINGS
rtpengine backports the same DTLS and socket fixes across four maintenance branches at once.
◆ Current state
Sipwise's rtpengine media proxy is maintaining several release lines in parallel (mr13.5, mr14.1, mr26.0, mr26.1, mr26.2), and most recent entries are coordinated backports. The September 16 batch fixes hash-table updates, nested string lookups and stop_forwarding mixups across four branches, and adds DTLS negotiation corrections (setup=actpass logic, ignoring incorrect DTLS=passive, keeping TLS IDs on answer role changes) to the mr26.0 and mr26.1 lines.
◆ Where it's heading
The work is focused on correctness in media negotiation, especially DTLS role handling and ICE on closed sockets, rather than new features. The newest branch, mr26.2, also brought AMR fmtp defaults, mirroring of generated RTCP sender reports to Homer, and recording cleanup hardening, which points to better interop and observability for carrier deployments.
◆ Prediction
More synchronized backport releases across the mr13.5 through mr26.2 lines are the clear pattern; feature work will most likely keep landing on mr26.2 first.
