Hi,

please check if the account has well registered.
Suggest you test with IP direct call, FAQ as below:

If the issue still exist, please kindly provide all THREE trace files to me:
a. Level 6 syslog

Hi Chris,

Sorrry for delay.
I double checked our internal database, and I found a similar case.

Please upgrade the firmware to below one and test again:

Let me know if any update.

Best Regards,
Travis
