Hi All, I’m trying to set up a PJSIP trunk between two FreePBX servers, but I’m not having much luck. Does anyone have a barebones config for a working trunk they could share? Thanks, Josh

You need to provide some more information. Is this going to be straight peering? Will one box register to another?

Hi, Yes, straight peering between two offices, both have static IPs, so I don’t think I need registration. Basically just looking for a PJSIP version of the IAX instructions

What have you done so far? You can show a screenshot of your trunk config. Are the two Freepbx servers connecting over the internet?

Come now, it’s simple. Trunk config on both PBXes: [image] Does not get much more “bare bones” than that.

@billsimon ’s Bare Bones™ setup will work, just make sure to match the SIP Server Port to the actual PJSIP port at the far end, which may or may not be 5060.

[image] lgaetz: which may or may not be 5060. It should be. There is really no reason for people to deploy anything else.

That is different. I was implying the mess that exists because of the two channel drivers, and that chan_pjsip should always be on 5060. Changing a port is security through obscurity, and that is not effective. Yeah, for now it will cut down on log chatter. But if it becomes standard that SIP is on…

Thank you @billsimon for this post. How do we leverage authentication and also make sure encryption (SIP TLS and Secure RTP) are enabled between these servers?
