Hi Razvan,
I need to register some clients in Opensips. Those clients will come from
different IP addresses.
Then, allow Opensips to redirect INVITES to those registered clients to
B2BUA gateway. In that B2BUA server there is an identical location entry
as per Opensips received.
Scenario is:
WebCliente--------- REGISTER ---------------------Opensips------SipEndpoint
\------- REGISTER---B2BUA
- WebClient is sending now two REGISTER messages to both B2BUA and
SipEndpoint
- Opensips must save() and replace Contact IP:Port to point to B2BUA
(that's the Contact change I would like to do)
- Then, INVITE from SipEndpoint to Opensips must search for this
registered user and then send the call to B2BUA
(not to WebCliente)
Do you think, it's not possible to update contact in location database?
