Are there any downsides to running both chansip and pjsip on a system?
In this article I read this in the comment section:
“However I would caution people against running chan_sip and chan_pjsip at the same time. I have found that there is at least one implementation of FreePBX where SSRC is reset on RTP packets when a chan_pjsip extension picks up a chan_sip call. This breaks the RFC for RTP and thus causes dropped calls.”
