Help with warning error on new install

I just started using FreePBX. We currently have an existing asterisk installation running on 1.4 with a Thirdlane frontend and we are having a lot of problems and support is terrible so I decided to try and port it to FreePBX. I originally installed FreePBX Distro 64-bit 6.12.65 using Asterisk 11 but then switched it to 13.

I am very early on the setup because I am learning as I go. I created two extensions using PJSIP on an Aastra 6757i and a Yealink T46G. Everything is working but I see this message in the console.

WARNING[8568][C-0000000c]: chan_sip.c:22230 func_header_read: This function can only be used on SIP channels.

I can’t find it anywhere so I don’t know what it means. Can anyone tell me if this is normal using PJSIP or is there something wrong with my config?

I’m really committed to replacing our existing system and I just want to make sure it’s working properly from the beginning.

Thanks in advance.

This is normal and can be ignored.

Thank you for getting back to me.
