the Trunk shows as ONLINE

however i get this error

[2022-10-30 10:21:18] NOTICE[14891][C-00000017]: chan_sip.c:19648 send_check_user_failure_response: Failed to authenticate device "CID"sip:[email protected];tag=633508921ba064c1 for INVITE, code = -1

Add the pjsip port to the grandstream settings. If chan_sip is still on 5060 and the grandstream is set to that port it will send requests to the wrong driver.

yea that was it i totally didn’t see the failed to authenticate said chan_sip
