Chan_pjsip.c:844 chan_pjsip_write: Can't send 10 type frames with PJSIP

Hi,

Every time I make a phone call, I get hundreds of WARNING errors in the Asterisk logs. The call goes through fine, I would just like to know is there a way to stop this. All of my extensions are PJSIP, because that’s the future of Asterisk according to to the internet. I’m running FreePBX v14 with Asterisk 13.17.2.

Any ideas?
