Hello,
The Diameter FQDN configured in Open IMS is used for Diameter Sh
requests: it does not intervene in the PUBLISH process.
Nevertheless, the Mobicents Presence Server can refuse the PUBLISH
requests if the Terminating IOI ( a realm present in the P-Charging-
Vector header)
is different from the one configured in Mobicents. The default value
for that parameter is "
mobicents.org" (hardcoded) but it can be
modified with PresenceManagement (I have to confirm the right name)
MBean.
Hope this helps.
Ismael
