A new feature has been added to OpenSIPS trunk and will be present
in the 1.7 release: topology hiding functionality based on dialog
module.
It is a lightweight topology hiding built as an extension of
dialog module. It does not change the dialog elements (to tag,
from tag, callid), but only strips and restores the headers that
contain topology information (Via, Record-Route, Route and Contact
headers).
Anca,
This sounds really neat! Thanks! Question, call-ids frequently contain
source IPs in them. Is there anyway to re-write those?
This topology hiding approach is based on dialog continuity - dialog is
not change (opensips acts as proxy, not like B2BUA) and some information
(Routes, contact, VIA) from messages are hidden.
Nevertheless, as everything is dialog based, the dialog must not be
affected, so dialog elements cannot be changed (callid, tags).
Regards,
Bogdan
