Source: trx Version: 0.5-4 Severity: important With the recently released version 5.2 ortp has been relicensed to GNU AGPL-3+. Since your package is GPL-2 it is my understanding that it may not link in ortp 5.2 until it is relicensed to either GPL-3 or AGPL-3.
Please consult with the upstream developer whether they are open to relicensing. If they aren't you face the decision of whether to maintain a fork of an older license-compatible version of ortp, remove trx from Debian or work around this in some other way. Ask on debian-legal if you have questions about the details of license compatibility and how to best handle this. I may raise the severity to serious at some point as this may actually be an RC bug. Regards. P.S.: I'm not subscribed to this bug, so CC me in every message I should see.
