When you configure a SIP trunk to authorise your traffic by IP address, our platform expects all traffic from that IP address to perform as a SIP trunk. This impedes a number of features of also using our SIP Users directly on our platform with SIP endpoints.
If you wish to combine SIP trunks and SIP Users in the same environment simply amend your SIP trunk to a user/password authenticated trunk. We will then be able to distinguish the traffic you are sending us and both SIP trunks and SIP Users will work as expected.
