Hi List
Imagine the following situation:
Two Kamailio registrar proxies handling the same domain. Location
Information synced via DMQ.
So if a device registers we don't know on which of the two registrar
proxies.
Core proxy is dispatching calls to either one of those registrars.
Core also performs AOR database lookup and adds an X- header telling
which AOR the call is destined to.
Registrar performs lookup of that AOR in the location database and
routes the call to destination.
Problem: The call could be routed to the the registrar which does
not hold the active socket to that client.
Solution: reg_fetch_contacts, cycle the contacts and append_branch if
the contact has a local socket.
Next Problem: I use a failure_route to sent the call to voicemail, if
not registered, busy etc. This would trigger, if we have no
local socket for the registration which is on the other
registrar. So I have to find a way to send the call to the
other registrar.
I guess I can append_branch a branch pointing to the URI of the
other registrar. This would then succeed in reaching the
device. Also using the failure_route would work this way if
we get a remote error from behind the other registrar or no
registration at all.
Next Problem: I use a branch trigger to remove undesired header I do
not want to send to the customer. Now imagine that AOR has two
contacts, one on registered on each registrar proxy.
So I end up with two destinations added with append_branch to
the destination set.
One points to the device of the locally registered customer
device, the other one points to the other registrar where to
find the other device.
I use a branch route trigger to remove the X- Headers towards
the customer.
But I need to X- Header containing the destination AOR to still
be sent to the other registrar.
Is there a way to trigger a branch route for only some of the
destinations added with append_branch? Or to trigger different
branch routes for different destinations in one set added with
append_branch?
Or am I doing this completely wrong and there is an easier way? ;-)
Mit freundlichen Grüssen
