Incoming SIP Trunking calls from Service Provider to Session Manager are failing because Avaya Session Border Controller for Enterprise (SBCE) is not sending a domain name in the TO, FROM and REQUEST headers.
What needs to be changed in SBCE to make this happen?
A . In SBCE GUI, navigate to Global Profiles > Routing. Edit the Session Manager Routing Profile to link to a URI Group, which has the To, From and Request Headers and Replace Action set to Overwrite with domain name.
B . In SBCE GUI, navigate to Global Profiles > Server Configuration. Edit the Session Manager server entry to set “Overwrite Domain Name”.
C . In SBCE GUI, navigate to Global Profiles > Topology Hiding. Edit the SessionManager_TH to change the To, From and Request Headers Replace Action, to Overwrite with domain name.
D . In SBCE GUI, navigate to Device Specific Settings > Endpoint Flows > Server Flows. Edit the Session Manager flow to change the End Point Policy Group to default-low.
