Hi Jayesh,
The dialog topology hiding works at dialog level and you cannot use it
in a per-branch manner. So, you cannot set or not topo hiding for some
branches. Solutions are:
1) simply do topo hiding when routing, so you will do it for all
branches.....
2) set a separate opensips instance (or spiral on the same opensips)
to do topo hiding.
Regards,
Bogdan

Hi All,
I tested the topology_hiding function in dialog module and it works
well. Now my scenario requires that I use topology_hiding function
based on the carrier where the call is supposed to go. And I use
failure_route to failover between multiple carriers. So the condition
is, if 1st carrier requires topology_hiding I enable it and route the
call and if that call fails, the next carrier might not need
topology_hiding enabled so I need to somehow undo the topology_hiding
that I called while routing to the first carrier.
Moreover, if I call the topology_hiding again for the second carrier,
the contact header gets malformed since the contact header is appended
again and the call fails because of invalid contact header.
One possible solution I thought of was calling the topology_hiding
function in the branch_route, but opensips would not start and logs an
error saying "Command cannot be used in the block".
Anyone with any possible workaround for this? Any help is appreciated !!
Thanks,
