Why recently can't make outgoing calls through Sipgate sip trunk?

[Issue Description]

The Sipgate sip trunk was working fine on your PBX, but recently when you make outgoing calls through the SIP trunk, then received '403 Forbidden' from the SIP provider, and at your IP phone got error '603 Decline'


[Applicable Models]

Yeastar P-series PBX



The sip provider has a request with the SIP Header



Please set the SIP trunk Outbound Parameters as below, and then please set the Outbound caller ID name as the Outbound caller ID for extensions under the Outbound Caller ID page.
