rtpengine vs Fourwaves: at a glance
What is rtpengine?
rtpengine backports a DTMF header-extension fix to mr26.0 and mr26.3.
Sipwise's rtpengine shipped a batch of SRTP, ICE, Opus and Redis fixes to four branches on November 2. Two days later, mr26.0.1.28 and mr26.3.1.3 carry a single fix that leaves room for the RTP header extension when adding DTMF packets.
What is Fourwaves?
Fourwaves doubles Free plan submissions to 50 and reworks reviewer assignment.
Fourwaves ships small dated updates most days. November 11 raised the Free plan from 25 to 50 submissions, and November 12 added a four-step Assign reviewers window. Earlier in November it brought offline mobile check-in for Pro organizers and saved email templates for Advanced and Pro.

rtpengine
5.0MEETINGS
rtpengine backports a DTMF header-extension fix to mr26.0 and mr26.3.
◆ Current state
Sipwise's rtpengine shipped a batch of SRTP, ICE, Opus and Redis fixes to four branches on November 2. Two days later, mr26.0.1.28 and mr26.3.1.3 carry a single fix that leaves room for the RTP header extension when adding DTMF packets.
◆ Where it's heading
The project ships fixes in synchronized batches across every supported branch and reserves new behaviour for the newest line. Recent work clusters on encryption correctness, ICE negotiation edge cases and Redis-backed call recovery.
◆ Prediction
Follow-up builds on these branches within days are likely, as after the October 16 batch, along with further mr26.3 builds.
Fourwaves
5.0MEETINGS
Fourwaves doubles Free plan submissions to 50 and reworks reviewer assignment.
◆ Current state
Fourwaves ships small dated updates most days. November 11 raised the Free plan from 25 to 50 submissions, and November 12 added a four-step Assign reviewers window. Earlier in November it brought offline mobile check-in for Pro organizers and saved email templates for Advanced and Pro.
◆ Where it's heading
Most releases go to organizer tools for running the event and the review process, with features gated to paid plans. The Free plan increase is the first move in this run that widens the entry tier rather than adding to paid ones.
◆ Prediction
Expect more steps in the submission and review workflow to follow the new reviewer window; whether the Free plan change is part of a wider pricing revision is unclear from the entries.
