Can pjsip and chansip be run simultaneously or does that cause issues with SSRC reset?

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.”

There’s been no reported problems to us about running both at the same time or interop between the two.
