res_rtp_asterisk uses pjproject for ICE, TURN, and STUN support. If it is detected on the system it will be built with support for it and res_pjproject.so must be loaded as well. Is this module not loading or something?

Since I use plain old SIP, I do not load PJSIP, i.e., in modules.conf I include noload=> for all modules prefixed pjsip. I have been doing this for years. This is the first version where this doesn't work.
So what PJSIP module should I load even if I don't use PJSIP? To be clear, I do not use PSIP, and many others avoid it as well, for one single reason: there is no known way to avoid proxying the media, and that us a killer for scalability. Whatever configuration yo use in PJSIP, if you do "rtp set debug on", the media is traveling within, while in plain old SIP, there is a way to avoid that in most cases, where all IP's are public. So basically for big companies, PJSIP is useless.
Please correct me if I am wrong.

The module that needs to be loaded is res_pjproject.so as I mentioned in my initial response.

You've previously stated that PJSIP is not a solution for your environment, I know of no work that has been done to do what you want.

Closing this out since it's a loader configuration issue.

Hi,

I came across this issue quite haphazardly and after having read the comment I just wanted to improve Joshua's answer.

If I understand well you're speaking of the {{directmedia}} and {{directrtpsetup}} options for {{chan_sip}}.
Though I am not aware of a {{directrtpsetup}} equivalent in {{pjsip}}, {{pjsip}} does come with the {{direct_media}} option (with several {{direct_media_*}} suboptions).

Hope this help !

Regards,
