Failed to call inbound to S-Series PBX through SIP trunk when the caller's caller ID is anonymous.


If you can find a similar line, especially the keyword YSGUESTIN in your CLI log. Then you have the same issue.

-- Executing [123456@inbound_trunk_YSGUESTIN:1] YsWalkContext("PJSIP/anonymous-00000002", "whitelist-inbound,123456,1,10111,inbound") in new stack

-- Executing [123456@inbound_trunk_YSGUESTIN:2] NoOp("PJSIP/anonymous-00000002", "NODNIS") in new stack

-- Executing [123456@inbound_trunk_YSGUESTIN:3] Goto("PJSIP/anonymous-00000002", "inbound_destination_YSGUESTIN,123456,1") in new stack

-- Goto (inbound_destination_YSGUESTIN,123456,1)


Disable the Allow Guest option on the SIP Advanced Settings page.
