OpenSIPS vs HOMER
A side-by-side editorial comparison of OpenSIPS and HOMER — release velocity, themes, recent moves, and the top alternatives to consider.
OpenSIPS vs HOMER: at a glance
What is OpenSIPS?
OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.
OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.
What is HOMER?
HOMER 11 closes an open mTLS listener and stops dropping ISUP from SIP-I calls.
HOMER's 11.0 pre-releases keep pairing security fixes with SIP-I decoding. 11.0.384 makes HEP and HTTPS ingest with mutual TLS and no CA refuse to start, where before they accepted any client, and runs all-in-one node reads in the DuckDB sandbox. It also stops the Decode window from dropping the ISUP part of multipart SIP-I INVITEs. 11.0.382 and 11.0.381 had already required tokens for the live SIP stream and admin rights for alert changes.

OpenSIPS
0.0MEETINGS
OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.
◆ Current state
OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.
◆ Where it's heading
The product is moving toward a 4.0 major release through a standard RC cycle. A second RC a month after the first suggests stabilization work rather than new scope, but the entries do not say what 4.0 changes.
◆ Prediction
A 4.0.0 general release is the next expected step; what it contains cannot be read from these announcements.
HOMER
5.0MEETINGS
HOMER 11 closes an open mTLS listener and stops dropping ISUP from SIP-I calls.
◆ Current state
HOMER's 11.0 pre-releases keep pairing security fixes with SIP-I decoding. 11.0.384 makes HEP and HTTPS ingest with mutual TLS and no CA refuse to start, where before they accepted any client, and runs all-in-one node reads in the DuckDB sandbox. It also stops the Decode window from dropping the ISUP part of multipart SIP-I INVITEs. 11.0.382 and 11.0.381 had already required tokens for the live SIP stream and admin rights for alert changes.
◆ Where it's heading
Three releases in a week closed access gaps, which suggests a security review of the 11.0 line before a stable release. Alongside it, the work on SIP-I and ISUP decoding points at carrier and telco users who bridge SS7 and SIP.
◆ Prediction
Expect more fail-closed defaults and sandboxing in the next 11.0 builds, and possibly a published advisory for the mTLS issue.
