What is your FW version of GSC3505? Please point to “” to upgrade to latest version and try again and report whether still have problem. If still have issue, enable SYSLOG to DEBUG, collect syslog, or capture a wireshark trace, open ticket at HELPDESK and asking Grandstream Support to help. Thanks.
